Doctrine holds paramount importance in defining the true path of faith and obedience to God. The Bible clearly states that God is not the author of confusion, and thus, He is not the source of doctrinal discord. Disagreements among clergymen, especially on critical matters like the Sabbath, portray a false image of God as unconcerned with doctrine, which contradicts His nature. False doctrine deceives and destroys both godly maturity and unity, scattering believers like leaves in the wind. It is through adherence to true doctrine, as given within the Church of God, that believers are equipped for every good work and prepared for the Kingdom of God. The Church of God stands as the pillar and ground of the truth, containing the doctrines necessary for salvation and spiritual growth. These doctrines are not merely intellectual concepts but are practical instructions that must shape daily conduct and attitudes. They provide the logical framework for understanding life from God's perspective, dissolving its mysteries and guiding believers to live as part of the body of Christ in every aspect of life. True doctrine, delivered as a specific package, aligns with God's purpose and leads to the correct conclusion for life, distinguishing the Church of God from all others. Fellowshipping with those who reject true doctrine, such as by observing Sunday in defiance of God's commandments, risks absorbing false teachings and losing one's spiritual identity. Such actions fail the test of faithfulness to Jesus Christ, as they seek fulfillment apart from Him. The fruit of false doctrines in other spiritual organizations has produced a world filled with the very evils God warns against, proving they are not the source of truth. Believers must remain separate, adhering to the true doctrines of the Church of God, to avoid being deceived by appearances of morality or social good that lack the foundation of God's plan. Christian doctrine transcends mere morality, focusing not just on behavior but on conduct and attitudes rooted in devotion to Christ, the Father, and the plan of redemption. It prepares believers to glorify God and witness for His way, aligning with the ultimate purpose of establishing His government and religion on earth. False doctrines in other churches, centered on worldly focuses rather than the Kingdom of God, lead to a different path and destination, as belief inevitably shapes conduct. Thus, doctrine makes a profound difference, and only through obedience to the true teachings within the Church of God can believers be prepared as first fruits for His return.

It is vital that true Christians believe and behave in accordance with God's doctrine. Jesus states unconditionally that true worshippers will worship the Father in spirit and truth, for the Father is seeking such to worship Him. God is Spirit, and those who worship Him must worship in spirit and truth. What we believe in our minds and feel in our hearts, we will perform in our actions. When based on truth, Christianity follows this principle, requiring genuine obedience to God's doctrines. Doctrine is of utmost importance to a Christian. Paul's repeated emphasis on sound doctrine implies that the body of teaching in the church is more than just a gospel about Christ; it is the gospel of Christ—what He taught and lived in His own life, and what He expects us to follow. His doctrine is the pattern of sound words, the body of truth, once for all delivered to the saints. God inspired the writers of the New Testament to warn us that His church must have a solid foundation in the truth of Christ to defend and contend for the faith against the constant bombardment of false doctrines. True Christian doctrine claims far more than mere insight into eternal truths: Jesus Himself tells us that He is the truth, not just a teacher of truth. More important than exposing false teaching, true doctrine is the teaching that will guide us to salvation. The truth reveals how to live in a way that will please God and instill in us the fundamental traits of His very character. Only by His doctrine can a person hope to find and remain on the path to the Kingdom of God.

The importance of doctrine in religious truth is a weighty matter for individual believers, as it is easy to fall into tragic flaws by assuming that Christ approves of erroneous beliefs. Doctrine shapes one's worldview, attitudes, and conduct, directly influencing the outcomes of life through the process of teaching, belief, action, and result. False teachings pose a grave danger, subtly eroding a person's belief system and altering choices, which can lead one astray from the path of Christ. Jesus Himself warned that the foremost concern at the end times would be deception through false doctrines, surpassing even the terror of wars, diseases, and tribulations. His caution in Matthew 24:4-5 emphasizes the need to guard against deception by those claiming to represent Him while teaching falsehoods about His way. The Bible clearly establishes that God does not lie, is not the author of confusion, and does not make war against Himself, as seen in Hebrews 6:18, Numbers 23:29, I Corinthians 14:33, and Matthew 12:25-26. This principle reveals that conflicting doctrines, such as those between Christianity and Islam, cannot originate from the same God of the Bible, as they produce confusion and warfare rather than peace. James 4:1-4 further illustrates that division and warfare within the church are evidence of a broken relationship with God, flowing from the influence of the ruler of this world rather than the Spirit of God. Similarly, I John 4:19-21 underscores that true love for God must manifest in love for one's brother, and a lack of such love indicates a carnal state or deception about one's connection to God. The historical pattern of humanity, beginning with Adam and Eve in Genesis 3, demonstrates the critical impact of what one is taught and chooses to believe. Their decision to accept false teaching led to a changed worldview and sinful actions, ultimately resulting in widespread wickedness and violence, as seen in Genesis 6:5 and 13. This cause-and-effect relationship, reinforced by Proverbs 26:2, shows that beliefs directly determine actions and consequences. Revelation 12:9 reminds us that all have been subjected to the same deceptive teachings as Adam and Eve, living in cultures permeated with distortions about God and His purpose, leading to a confusing array of religions worldwide. Jesus' warnings in Matthew 16:6 and 11-12 against the leaven of false doctrines remain relevant, as the danger of destructive teachings persists, only with different groups involved. Modern so-called Christians often feel free to alter biblical teachings, disregarding clear statements from Christ in Matthew 5:17-19 about the enduring nature of the law, in Matthew 6:24 about the impossibility of serving two masters, and in Matthew 7:13-14 about the narrowness of His way. Luke 14:25-27 further sets strict terms for discipleship, sometimes requiring significant personal sacrifices. Acts 4:11-12 and multiple references in Acts affirm Christianity as a distinct way of life, separate from other religions by its doctrines and practices. Recent polls reveal a troubling trend among those identifying as born again Christians, with many embracing beliefs contrary to biblical doctrine. Twenty-six percent believe all religions are essentially the same, ignoring the exclusivity of the Christian way as described in Acts. Fifty percent think good works alone can lead to heaven, negating the necessity of a Savior and the principle of salvation by grace through faith. Most staggeringly, thirty-five percent do not believe in the resurrection of Jesus, a foundational truth for salvation as stated in Romans 10:6-9, which declares that without belief in His resurrection, there is no hope or salvation. These deviations illustrate the peril of creating personal religions, mirroring the prideful rebellion of satan, and highlight the profound ramifications of choosing to believe outside of God's teachings, as such choices inevitably shape actions and lead away from b

The truths of the Word of God are eternal, never-ending in their validity, and can always be trusted, reflecting the unchanging nature of God Himself. As stated in Malachi 3:6, the Lord declares, "For I am the LORD, I change not; therefore you sons of Jacob are not consumed," affirming His steadfastness in fulfilling promises despite human faithlessness. Similarly, Hebrews 13:8 confirms that Jesus Christ is "the same yesterday, and today, and forever," embodying the way, the truth, and the life as He taught and lived. In contrast, human nature often rejects these eternal truths when they demand sacrifice or change, as seen in the Pharisees who trusted in their own righteousness, as noted in Luke 18:9. Throughout history, from the ancient Greeks to the Israelites, and even among early Christians, there has been a persistent tendency to reject God's truth in favor of personal opinions or cultural influences, leading to spiritual destruction. This pattern continued in the church after Jesus' death and resurrection, where some converts clung to Gnostic teachings despite having God's Spirit, defiling the church with lies. In the 20th century, similar doctrinal shifts of Gnostic origin within the Worldwide Church of God led many astray, showing that the danger of rejecting truth persists. God's Word provides structure and guidance for daily life, as seen in Psalm 119:1, which blesses those who walk in the law of the Lord, encompassing the whole of God's revealed will. This law, synonymous with the Word of God, is pure and infallible, as Solomon writes in Proverbs 30:5, "Every word of God is pure: He is a shield unto them that put their trust in Him." Unlike Gnosticism, which lacks structure and allows individuals to set their own standards, true Christianity clearly spells out the works we are created to perform, as Ephesians 2:10 states, "For we are His workmanship, created in Christ Jesus unto good works, which God has before ordained that we should walk in them." Examples like Abraham, who obeyed God's voice and kept His commandments, and Jesus, who unequivocally kept His Father's commandments, demonstrate the importance of adhering to God's eternal truths. Ecclesiastes 12:13-14 concludes that fearing God and keeping His commandments is the whole duty of man, against which every work will be judged. In these pressure-packed times, Jesus warns in Matthew 24:23-26 against deception, emphasizing the need to discern truth amidst a flood of misleading words from the serpent, aimed at destroying those who know the truth. Thus, the doctrine of God's Word remains vital, guiding Christians on the narrow and difficult way, providing a clear path to follow amidst worldly and satanic influences.

The importance of doctrine cannot be overstated, as it fundamentally shapes one's worldview and decision-making. False teachings from ancient philosophers like Orpheus, Pythagoras, Socrates, Plato, and Ptolemy have infiltrated the church, blending with biblical truth and persisting into modern Christianity. These erroneous doctrines, including evolution, the immortality of the soul, eternal security, purgatory, predestination, reincarnation, astrology, antinomianism, and progressive revelation, distort the true faith and lead believers astray. Such beliefs, rooted in human reasoning rather than God's Word, have practical consequences, rendering sin inconsequential and diminishing the need to resist temptation or grow in knowledge of God. The doctrine of the immortality of the soul, a cornerstone of paganism, deceives by suggesting inherent eternal life, undermining the urgency to overcome and submit to God's laws. Dualism, another pervasive error, falsely divides the universe into matter as evil and spirit as good, contradicting the biblical truth that all of God's creation is good. This leads to neglect of the body, seen as temporary and unimportant, despite Scripture declaring it the temple of the Holy Spirit, which we are charged to care for. The persistence of Gnosticism, a collection of philosophical and religious concepts brought into the church by converts, continues to challenge the purity of doctrine, as seen in the apostles' writings and the ongoing struggles within the church today. Adhering to revealed truth is essential to avoid being ensnared by these deceptive teachings and to maintain the integrity of the faith delivered to us.

The importance of doctrine cannot be overstated, as it fundamentally shapes our relationships and spiritual lives. A lack of true conversion, rooted in correct doctrine, is often the source of many marital and personal struggles. Faith in God and alignment with His teachings provide the solution the world desperately seeks, though it remains unaware of this need. When Jesus Christ returns, the primary task in the World Tomorrow, after initial conflicts are resolved, will be to convert people to God's way of life, ensuring past mistakes are not repeated. This conversion will liberate individuals from fears, jealousies, and desires that dominate the current evil world, enabling them to live abundant lives. Doctrine must be based on the simplicity and directness of God's word, as highlighted in II Corinthians 11:3. God's teachings are not convoluted or filled with hidden meanings; they are frank and accessible to those called by His spirit, though hidden from the world. The carnal mind, as described in Romans 8:7, resists God's law due to enmity and human vanity, often leading to misunderstandings of clear scriptural instructions. Correct doctrine does not require complex technical manuals or extensive libraries; God has ensured His word is understandable to a called, careful, and normally educated person. Examples such as the timing of Passover and the Wave Sheaf Offering illustrate how some fail to accept the plain meaning of scripture. Leviticus 23:4-6 clearly states that Passover is on the 14th day of the first month, distinct from the Feast of Unleavened Bread beginning on the 15th. Yet, some blur these distinctions by observing Passover at the end of the 14th, leading to a historical blending of the festivals' teachings. Similarly, assumptions about the Wave Sheaf Offering in Joshua 5 lack scriptural support, as no such offering is mentioned, and conditions for offerings, as outlined in Deuteronomy 12 and Exodus 23:16, were not met since the Israelites had not sown the land. God's strict regulations, as in Deuteronomy 12:32, forbid adding to or diminishing from His commands, emphasizing the need to adhere to clear scriptural directives without assumptions or elaborations.
