Salvation Process

Richard Ritenbaugh, observing that pagan fertility rites and sun worship have nothing to do with the resurrection or ascension of Christ, asserts that Christmas, Easter, as well as the concepts of "amazing grace," and "unmerited pardon" are far cries from the Bible's definition of Christianity. Because he sought to avoid the appearance of endorsing the syrupy cheap grace advanced by Protestant thinkers, Herbert W. Armstrong de-emphasized the birth, resurrection, and ascension of Christ. As a result, the Church came to lose some valuable insights about those events. Neither Christmas or Easter appear in the Feasts of the Lord (Leviticus 23), but we find plenty of emphasis on the resurrection and ascension of Christ in the Holy Days. The wave-sheaf offering, for example, appearing between Unleavened Bread and Pentecost and symbolizing the Father's acceptance of Christ as First of the First Fruits, provides the means for our ultimate acceptance as First Fruits as well. Christ's ascension enables Christ to serve before the Father as our High Priest, mediating between man and God. It also facilitates 1.) His gifting the Church for equipping the saints, 2.) His pouring out the Holy Spirit on us, 3.) His aiding us when we are tempted, 4.) His healing us when we are sick, 5.) His guarding us from the evil one and 5) His preparing a place for us in God's Kingdom. Realizing that the apostles wrote frequently about Christ's resurrection and ascension, we must be willing to share their perspective.

Richard Ritenbaugh, using the metaphor of "balancing" a checkbook, wherein two totally distinct documents, the user's register and the bank's statement are squared, or brought into agreement, explains Christ's work of "squaring" us—that is justifying us - before God. Through one man (Adam), mankind was condemned, but through Christ (the second Adam) we are justified and reconciled. After reconciliation, there can finally be a meeting of minds as we are fashioned into a new creation, invited to sit in heavenly places. As a work in progress, created for good works, we will ultimately be just like Him. If we faithfully use His Holy Spirit, we will be part of the first-born, qualified to receive our inheritance of eternal life in the family of God. Christ's work at Calvary reconciled us to God, setting in motion a process which will eventually bring the entire creation into reconciliation with God the Father. Currently, the entire creation groans in agony awaiting the liberation from corruption. The Feast of Trumpets anticipates the return of Jesus Christ to this earth, having resurrected the dead saints and receiving the living saints at His coming, a day which harkens back to the time when the Law was originally given to the Israelites, a time when Mount Sinai was covered with smoke, when trumpets resounded, and the people were terrified, shocked to learn how powerful their God really was. The events preceding Christ's return will be exceedingly terrifying to those who oppose Him, but welcome to the displaced remnant who will finally be allowed to return to their homeland. God will then pour out His spirit upon them, rendering their hearts pliable, submissive, and deeply repentant for their transgressions.

John Ritenbaugh somewhat modifies his amazement at individuals who made gigantic sacrifices in the fledgling days of the Radio Church of God, concluding that it is in fact God who expends the lion's share of the energy, putting us all through flip flops in our sanctification process. Our yielding to God's will is a relatively minor sacrifice compared to what He does continually on our behalf. In no way are we interfacing with a passive God, but instead with One extremely active in our lives from before the foundation of the world. As the destinies of the major biblical luminaries were predestined, so are all the lives of God's called-out ones. God does the choosing; God does the moving, micro-managing the lives of those He has called as His servants (such as Abraham, Isaac, Moses, etc.), protecting us from the hatred of the Gentiles (emanating from the spirit of Satan), who are jealous of the hedge of protection and prosperity (both resulting from grace) God has given Jacob's descendants, the current custodians of the prosperous western world. God set apart (that is, made holy, sanctified, and metaphorically married) the entire physical nation in order to model His Laws and way of life to the rest of the world. Physical Israel failed in its responsibility, squandering its precious blessing. God destroyed the physical Temple, national Israel's "security blanket," but concomitantly began building, under Christ, another temple, this one made up of called-out believers. (In a supplemental metaphor, these believers represent Christ's Body, wherein the Holy Spirit dwells.) Whether seen as a body or a temple, these called-out believers represent a new institution, an entity distinct from the previously set-apart nation of Israel. This new institution will eventually have a holiness on a vastly highly plane than that of physical Israel, as it will come to possess the very holiness of God Himself. No one can come to this level of rel

David C. Grabbe:  Time-lapse cinematography—such as a five-minute video clip composed of 100,000 slightly different pictures—is a useful way of understanding how each moment of our lives relates to the overall progression. So even though a present "snapshot" of our lives looks dismal, it cannot reveal what happens next. ...

John Ritenbaugh, continuing his exposition on the source of the Church's characteristics, reiterates that Jesus Christ is the architect, suggesting that the created institution or body must take on the characteristics of the builder, following assiduously His Commandments, hallowing the same Sabbath and Holy days that He did, and reflecting His character. Jesus Christ has handpicked those He wanted, gifting them with abilities to carry out their responsibilities, a process that has been underway for 2000 years, leading to a cumulative 144,000 beings, constituting the First-fruits and Bride of Christ, prepared to assist Him in governing. Those whom God has called are created in His image, but they are not yet of the God-kind until they receive a tiny portion of His Holy Spirit, enabling them to resist the carnal human nature with which they have been born. As God's Spirit displaces carnality, we become a new creation in Christ, born from above, developing godly character and displacing human nature. In developing and building character, we must voluntarily choose to obey, but God does virtually everything, giving us the will and power to work with His Holy Spirit. Spiritual birth occurs within the human heart—a total transformation of the human heart by the immaterial power that motivates us to acquire His characteristics. This transformation does not take place all at once but requires a lifetime to remove all the impurities. As the impurities are refined out of our character, the world will begin to hate the new creation being formed in us and will feel compelled to hatefully persecute us. We have no idea what God is doing with us as He begins to shape and mold us, but we need to remember that He owns us. As Adam contributed nothing to his physical creation, we contribute nothing to our spiritual creation except for our willingness to yield to His workmanship. The characteristics of the Church are being (and have always been) formed from on high.

In Philippians 2:12, the apostle Paul encourages us to work out our “salvation with fear and trembling,” and Peter tells us to “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (II Peter 3:18). ...

John Reiss:  We sometimes take for granted what a precious honor it is to have been included in God's plan of salvation. To think that God chose us from the billions of people who have ever lived and opened our minds ...

David Grabbe, cuing in on II Peter 3, asserts that there are good reasons why Christ has not yet returned, reminding us that scoffers and false teachers will test the faith of those who once accepted the truth. Some will yield to their natural desires, finding an excuse to forget about their commitment to God. In their desire to live for the moment, the warnings of the prophets will fade into ineffectiveness. We are in danger of becoming desensitized to righteousness. We need to keep a long-term perspective, suffering long while our Elder Brother Jesus Christ tends to our process of repentance until we finally become fully in His image. Jesus Christ will not wrap things up until we have completed our process of salvation. All material things will dissolve, to be replaced with a new Heaven and Earth in which righteousness will dwell. This world is passing away; we must focus on permanent spiritual priorities, reflecting God's righteousness in our lives. When Christ returns, we cannot be at odds with Him in any manner, but must have been following through on the salvation process, putting our spiritual houses in order.

John Ritenbaugh, fearing that we may be following suit in the world's religions by focusing on "getting salvation" rather than preparing for service in God's Kingdom, cautions us that we must re-orient our mindset, seeking to grow in the stature of Christ. Many mainstream religions believe that much of the "pesky" rules of the Bible have been 'done away.' We dare not 'do away' anything that is part of God's mind, or we will not be in His image. In judging, one size does not fit all. Some of the Commandments are more important than others, but they are all important. Acts 15 did not give Gentiles exemption from keeping God's Law. The laws of clean and unclean were not done away, but the vision Peter saw was given so that he would not judge Gentiles as common. The "yoke" Peter described in Acts 15:10 was not the Old Covenant laws, but rather Pharisaical regulations which were not a part of the Old Covenant. The Sabbath, Holy Days, and Clean and Unclean laws were not done away; the sacrificial system will be re-instituted for a time in the Millennial setting. We have been commanded to pursue holiness, moral purity, a necessary quality to grow into God's image. The term holy, in every context, does not always mean morally pure, but instead to cut something, or to set apart from the group. The term Greek haggios, however, denotes moral purity, only possible through God's Holy Spirit, enabling us to become partakers of the Heavenly calling, justified by Christ's blood, faithfully keeping the Commandments of God in the footsteps of Jesus Christ. Those who have been called now have an advantage over the ancient Israelites, having power to faithfully keep God's Commandments (written indelibly in our hearts), motivated by His Holy Spirit. Holiness encompasses all of what was written in both the old and new covenants.

God's grace is so wonderful and undeserved that, to many of us, it is almost unfathomable. Perhaps we have such a hard time understanding it because we tend to think of it as a "thing" that God dispenses. John Ritenbaugh shows, however, that "grace" is a term that represents God's awesome generosity toward us, His continuously flowing blessings and saving acts.

The images that Jesus used to explain the spiritual birth of a Christian have confused many down through the centuries. John Ritenbaugh explains His use of "wind" and "Spirit," as well as the concepts of "Jerusalem above" and "firstborn" in relation to the born-again doctrine. The Bible consistently compares Christians to already-born and maturing children or adults.

Richard T. Ritenbaugh:  A great deal of confusion exists--even among professing Christians--about true conversion. Contrary to many who teach it, confessing the name of Jesus is not how the Bible defines a converted person. ...

The brain is unquestionably the most complex organ of the human body. It is also the most important ...

What many religious people do not seem to understand is that justification before God is just the beginning of something far more involved—and that is living by faith. John Ritenbaugh covers the faithful life and work of Noah, illustrating that walking by faith with God is a practical responsibility.

John Ritenbaugh reiterates that God is a working God, creating holy, righteous, divine character with the goal of recreating man in His image. From the time of our justification until our glorification in God's Kingdom, it almost seems 'downhill,' with sanctification being a difficult road. Works are not only required during sanctification, but they determine to a great degree the magnitude of our ultimate reward. We are God's creation, created for good works. As the clay, we must allow God to mold us into whatever He wants, cooperating with Him until we are fully in the image of His Son, a brand new spiritual creation. Until then, we are commanded to make life-and-death choices, with the emphatic admonition of choosing life or putting on Christ and putting off the old man. We are begotten children of God, protected within the metaphorical womb of the church, until the spiritual birth at our resurrection. We are also metaphorically a work in progress, as in the construction of parts of a building. Ultimately, all individuals who have ever lived will be judged according to the quality of their works; people will be judged according to what they do after they make the covenant with God. Works are required and rewarded.

John Ritenbaugh claims that the harshest criticism we receive is for our position opposing the doctrine of eternal security, having the audacity to suggest that works are required for salvation. I Timothy 1:8 indicates that the Law is good only if we use it lawfully. Philippians 2:12 indicates that work is required. Romans 13:11 indicates that salvation is not yet a done deal. Satan, having a perennial pattern to his deceptiveness, first proposes this deadly eternal security doctrine in the Garden of Eden, assuring Adam and Eve that they need not fear death (evidently because they had immortal souls). To one having God's Holy Spirit, committing sin is more dangerous because there is far more on the line. The Firstfruits will not get a free pass into God's kingdom. As the past history of creation unfolded, God demanded that choices indicating willingness to obey be made within the family of angels. When human beings were created, they had to pass a similar test, making life and death choices whether to obey or not to obey God's Government. We have a reciprocal responsibility in the wake of Christ's sacrifice to love God and keep His Commandments, living by every word of God. The God of the Bible is a working God never running out of useful and exciting projects, overseeing His works and creating dynasties, progressively working salvation in the midst of the earth, providing us an example and a mandate to participate in His endless creative work.

Martin Collins asks what we can do to improve our manners or etiquette. Our manners express our personality, especially as they portray humility, courtesy, or gentleness. The apostle Paul indicts all of us as lacking in courtesy before we were called. Now we must display the work of salvation, involving the etiquette and courtesy shown in the behavior of our Savior. Before our calling we did not possess these traits. Afterward, we go through a process of sanctification to develop the fruit of God's Holy Spirit and go on to perfection. Good manners, etiquette, and character may be improved by 1) trying to understand the other person's point of view, 2) paying attention in the little things, 3) making sure we keep our commitments, 4) clarifying what our expectations are, 5) always showing personal integrity, 6) apologizing for failing to keep our word or letting another person down, 7) and showing unconditional love.

The Bible makes it very plain that salvation is by grace, but it is also clear that we are 'created in Christ Jesus for good works' (Ephesians 2:10). Having explained justification, John Ritenbaugh tackles the process of sanctification, showing that the far greater part of God's saving work in us occurs after baptism!

John Ritenbaugh asserts that after justification, for grace to be made dominant, its influence must extend beyond justification, into the sanctification stage where the believer must yield himself to righteousness, keeping God's commandments making himself a slave of righteousness. God's grace is manifested by His giving gifts, carrying us forward, making it possible to be transformed into the image of His Son. Our responsibility is to walk where God leads us, realizing that He is the one always out in front doing the creating, putting forth energy to make something happen—the change of our heart. Only those yielding themselves to the New Covenant will receive this transformation—a miraculous new creation, patterned after Christ's spiritual image. In the whole sanctification process, it is God working in us to will and to do.

John Ritenbaugh assures us that God is involved in the minute details of every converted person's life just as much as He is in the major historical world events. As a new creation of God (II Corinthians 5:17) we receive continuous, meticulous, detailed attention through the creative activity of His grace which never stops. God, as Creator, takes the initiative (as the potter over the clay) for the elect's salvation, enabling us to build the repertoire of habits called character. In this process, bringing certain things together in the lives of the called, both calamitous as well as positive, God fulfills His purpose. Even though we don't at times know where we are headed, we need to develop the faith or trust in God's vision for us.

Are we "once-saved, always-saved"? Once God grants us His grace, are we assured eternal life? Richard Ritenbaugh exposes the fallacies of this Protestant doctrine of "eternal security."

Richard T. Ritenbaugh:  We frequently perceive characters in books as one-dimensional, and if we are an imaginative and comprehensive reader, perhaps in two dimensions. ...

We live in a society where both food and information are readily available. John Ritenbaugh asks, "What is our approach to them? How are we using attitude toward and application of them makes all the difference.

John Ritenbaugh cautions that we may have had a somewhat incomplete understanding of the symbolism of eating unleavened bread, exaggerating the importance of our part in the sanctification process. Egypt is not so much a symbol of sin as it is of the world or the location of our bondage. Leavening represents those elements of the world we are to leave behind- symbolic of every weight which encumbers our spiritual progress. Symbolically we eat unleavened bread because of what God has done- not what we have done. Eating unleavened bread symbolizes following God, displacing sin by doing acts of righteousness. God's total involvement in the whole sanctification process makes it impossible for any flesh to glory in His presence.

John 6 has always been a difficult chapter to explain. However, within his series on the physical/spiritual parallels in the Bible on eating, John Ritenbaugh shows how clear Jesus' teaching is and what it means to us.

In this Feast of Trumpets message, John Ritenbaugh reiterates that salvation is not a one time event, but a continuous process analogous to the birth process—not just immunity from death, but a total dramatic transformation of our nature into a totally new creation. Six major reasons why works are necessary (following the initial justification stage) include: (1) to undertake godly character building and preparation for God's Kingdom; (2) to give evidence of our faith; (3) to witness to the world that God is God; (4) to glorify God; (5) to prepare for a reward; and (6) to exercise living faith toward a covenant partner who has been eternally faithful.

Richard Ritenbaugh reiterates that the Kingdom of God or of Heaven has past (Hebrews 11:13), present (Hebrews 12:22), and future (Hebrews 12:28) aspects. The Kingdom parables primarily provide instruction for the present aspect, a time when struggle and suffering are part of the mix (Matthew 11:12). The first parables of Matthew 13 reveal Satan's battle plan to: (1) attack in the early stages of development, (2) infiltrate with secret agents, (3) cause the church to grow large and worldly, exceeding God's prescribed limits, and (4) corrupt by false doctrine, destroying the relationships between the brethren. These parables describe the last quarter century in the church of God.

John Ritenbaugh stresses that salvation is an entire creative process undertaken by God to justify, sanctify, and glorify a called out body of individuals. Ephesians 2:8 uses the perfect tense 'saved,' indicating an action started in the past and continuing on into the present. As with the typology of the Israelites 'saved' from bondage, the process was not completed until a remnant made it to the promised land—with the sobering example of many dying in the wilderness. Likewise, we are warned about the dangers of backsliding and resisting God's will (II Peter 2:20; Hebrews 10:31) rendering the erroneous 'once saved, always saved' assumption a foolish and dangerous misconception. God assumes the burden for our salvation, but we are obligated to yield to His workmanship—made manifest by good works—the effect rather than the cause of salvation.

John Ritenbaugh emphasizes that works are not the cause of salvation, but instead are the effect of God's creative efforts at bringing us into His image—a new creation. We are created in Christ Jesus, given a tiny spark of His nature from which to draw spiritual nourishment and receive our power to act. In this context, works are nothing more than our puny efforts to respond to God's love by voluntarily living like God does. The perfect tense of the verb 'saved' in Ephesians 2:8 (denoting an action started in the past and continuing in the present) does not guarantee that we will always remain in that state, but only if we continue to yield to God's shaping power, mortifying our human nature, and conforming to His image.

John Ritenbaugh stresses that good works are something that take place after the process of salvation has begun. Good works are the effects of God sending forth His Spirit and deliverance, but the works are not the cause of our deliverance. God's creative effort did not end with the physical creation or our election, but God continues to work, giving His called out ones the motivation and the power to do His will (Philippians 2:13) to the end that we might exemplify His workmanship (Ephesians 2:10)- a new spiritual creation shaped and patterned after God's image, having the ethical and moral character of God.

Have you ever wondered what "all in all" means in relation to God and Christ? John Ritenbaugh explains how this term has great significance to us today!

How does God define the church? What comprises it according to the Bible? The ekklesia, the Greek word translated "church" in the Bible, is not a humanly defined corporation, but the mystical body of Christ, having the Spirit of God. The true church of God is an invisible, spiritual organism, of those people that have and are led by the Spirit of God. And such a person will not turn away from the teaching delivered by the apostles.

Are you saved already or are you being saved? What is salvation anyway? What part do we play in our own salvation? These are important questions that we must answer from God's Word.

John Ritenbaugh clarifies some difficult terms which Protestant theologians have misapplied, characterizing God's holy law as a "yoke of bondage." If we fail to realize that Paul's focus in the Galatians epistle was justification (rather than the whole salvation process of sanctification and glorification) we could become confused. The Old Covenant had no provision for justification nor did it provide a mechanism to change the heart. The antinomian argument ignores that Christ also puts a yoke of responsibility on New Covenant participants (Matthew 11:29-30). The yoke of bondage Paul referred to was a syncretism of Halakhah- the code of regulations added by the Pharisees- and Gnostic ascetic ritualism, neither a part of God's Law. God's Spirit and law keeping are not contradictory.

We know the holy days typify the steps in God's plan. What happens between Pentecost and Trumpets, the long summer months? John Ritenbaugh expounds on the subject of sanctification.

John Ritenbaugh uses an analogy of a 1910 automobile as opposed to a modern one. Obsolete doesn't mean, as Protestant understanding would have it, "done away." The fault of the Old Covenant was with the hearts of the people. Christ took it upon Himself, with His death, to amend the fault enabling us to walk in the light, keeping the commandments. Salvation and conversion is a cooperative effort between God and His called-out ones, requiring both a calling and a response (justification and sanctification), a circumcision of the heart, imposing responsibilities on the participants of the covenant. Though the process took a unilateral act of sacrifice on behalf of the Testator to make it work, God demands of us unconditional surrender.

John Ritenbaugh explains that justification is not the end of the salvation process, but merely the doorway to a more involved process of sanctification, symbolized by the long journey through the wilderness toward the promised land, a lengthy purifying process involving Christ's work (of regeneration- making us pure) and our work of applying God's Word to our lives, enabling us to get all the spots and wrinkles out of us. Like the outward signs of a woman's pregnancy, sanctification is the part of the process where we bear fruit, giving visible evidence of God's Holy Spirit working in us.

John Ritenbaugh reminds us that under both the Old and New Covenants, refusal to keep to keep God's Law severs our relationship with Him. Like loving parents who give rules to their children to protect them from danger, our Loving Father has given us His Spiritual Law to protect us and bring us quality life. In the manner of Satan the Devil, who convinced Adam and Eve that God's commands restricted freedom, the misguided proponents of the anti-law bias or mentality have convinced many in our former fellowship that the Sabbath, the Holy Days, tithing, and food laws are harsh and restrictive elements of Old Covenant bondage. New Covenant justification does not do away with God's Laws (nor with human nature or carnality for that matter) but creates the circumstances through which faith is enhanced, producing sanctification and purification, bringing God's purpose (to restore all things) to perfection.

John Ritenbaugh, reflecting on man's ultimate destiny to have dominion over the entire universe, admonishes that preparation for this awesome responsibility requires faithful stewardship over the things God has entrusted to us (our bodies, families, possessions, etc.)—dressing, keeping, and maintaining those things, overcoming and growing, building character, and making use of the gifts God has given us. Though salvation along with the will and power come from God, the character must come from our effort at overcoming. In the seeming delay of the Bridegroom, we must rouse ourselves from our slumber and diligently prepare for His return.

In this Passover message, John Ritenbaugh observes that the world's religions are in abject bondage to falsehood because they do not observe the Passover. Freedom comes to God's called out ones incrementally from continuing on the way- the relationship between God and us. It is this relationship which is the most important thing Christ has died for. We need to be sobered at the awesomeness of the cost to set us free from sin- how far Christ was willing to be pushed. Immense have been the preparations for our ransom- involving billions of years (Hebrews 11:3, I Corinthians 10:11) and the death of our Savior. Because we have been purchased, we have an obligation to our Purchaser.

John Ritenbaugh focuses upon the pouring out of water as a symbol of the pouring out of God's Holy Spirit during the Second Resurrection. The vast majority of people who have lived on this earth have never heard the true Gospel of God's Kingdom. God, not willing that any should perish, has a timetable, carefully calculated to allow people to receive and respond to the truth at their maximum opportunity for salvation, each in his own order. The Judgment indicates a process, requiring considerable time, a turning point, leading to a just and equitable decision. This conversion process, requiring the use of His Spirit, symbolized by water has already begun for God's called-out ones. Without the quality of life imparted by God's Holy Spirit, eternal life is not worth living.

John Ritenbaugh insists that if mankind is separated from one another, it is also separated from God. Moreover, atonement with God will occur when mankind loves one another, loving as an action rather than simply a feeling. Contrary to the antinomian position taken by many Protestants, repentance—something that Christ does not do for us alone—is something we must do with the precious free moral agency God has given us. As sin brought a change in perspective and separation to our parents Adam and Eve, repentance, in one sense, brings us back to Eden—to the tree of life (via God's Holy Spirit). Reconciliation is an ongoing process enabling us to draw closer to what God is, having His mind installed in us.

John Ritenbaugh points out that Jesus Christ, through His voluntary humility (giving up all the perks of being God), has given us a model of the mindset that we need to have in order to attain membership in the family of God. Paul, desiring the Philippian congregation to attain spiritual maturity, urges that they (and we) take responsibility for the nuts and bolts process of overcoming or renouncing our carnal selves (working out our own salvation by the practical application of head knowledge) upon ourselves, cooperating with the shaping power of God (giving us the power to will and to do by means of His Spirit), who desires that we learn in the here and now the style of life (in a climate or environment of love as well as fear of soiling the family name of God) we will live for eternity.

John Ritenbaugh reiterates that the people who were preaching Christ from questionable motives were church members and not Judaizers, as some have assumed. Paul experienced a dilemma wondering if it would be better to suffer martyrdom, finishing his life's calling or remain alive to help the Philippians bear more spiritual fruit. Paul and the Philippians had mutual affection and respect for one another. Paul, after encouraging this congregation, assures them that their spiritual growth depended on their personal relationship with Christ, urging them to stand fast in the unity of the truth, being loyal citizens of the Kingdom of Heaven as Philippi was a loyal colony of Rome. Paul, assuring them that God is with them, providing everything they need to overcome, teaches that individual overcoming in lowliness of mind, putting others ahead of self, leads to the whole body being strengthened.

John Ritenbaugh focuses upon Paul's motivation for his letter to the Philippians, both appealing for unity and offering encouragement, reminding them that their relationship with one another was through Christ. Unity could only be maintained if they prayed for one another, exercising reasoning, discerning, and discriminating agape love. Paul encourages the Philippians, assuring them that his own incarceration (apparently engineered by God) had turned out for the best, enabling him, exuding his cheerful personality, to provide one—on-one testimony to a succession of guards, enabling God's witness to get to the upper echelons of the praetorian guard, greatly extending or amplifying the witness. Regardless of the precariousness of his ostensibly grave circumstances, Paul, with deep conviction, expected spiritual deliverance.

Can a Christian commit a sin, and still be a Christian? Or would this be "the unpardonable sin"? Or would it prove he never was a Christian? Thousands worry, because they do not understand what IS the sin that shall never be forgiven.
