Faith is essential because without it no one can even be saved, yet the world has almost lost sight of it, as Jesus' question "shall He find faith on the earth?" foresaw. Jesus Himself did His miracles not by His own power but through faith, with the Father working in Him by the Holy Spirit, and the same power was available to the apostles and may be available today. It is lacking now because minds are absorbed in material things and distant from God through too little Bible study and earnest prayer. Faith, defined by Hebrews 11:1, is the assurance and evidence of things hoped for and not yet seen. It precedes possession and has nothing to do with the five senses, feelings, or impressions. Using the image of a courtroom in which God is tried over an unanswered prayer for healing, the source argues that physical evidence such as lingering pain must not outweigh trust in God's written promises, since God cannot lie. God has not promised when or how He will answer, and He may delay in order to try faith and build patience (James 1:3). Faith must therefore continue steadfastly until He acts. God's will can be learned from Scripture, so one should claim His promises boldly, rely on His Word, and stop straining to work up faith. Faith itself is God's gift (Ephesians 2:8), the very faith of Jesus placed in believers. It grows by drawing close to God through surrender and much prayer.

Faith is the victory that overcomes the world, and it is indispensable: without it no one can please God or qualify for His Kingdom. Drawing on I John 5:4-5, the world is far stronger than anyone born into it, so overcoming requires a power beyond natural ability. That power comes from new birth and from a living connection to Jesus Christ. Faith is God's gift, received through hearing His Word (Romans 10:17), and it is the conviction that Jesus is the Son of God. It works in two ways. Passively, believers run to Christ as a strong tower and rely wholly on Him (Proverbs 18:10, John 15:5, Philippians 4:13). Actively, they work faith out in obedience, since faith without works is dead (James 2). Faith also lets converted people see the world's true nature, so they do not trust politics or worldly philosophies. Faith can be eroded by demanding to know why God allows trials or how He accomplishes miracles. Peter sank because he looked for physical sensation instead of trusting Christ. Faith must accord with God's will and trusts Him without needing to feel or understand. Hebrews 11 shows that faith is assurance of things hoped for, which treats the future promise as present, and the saints died in it. Jesus said the work of God is to believe in the One He sent (John 6:29). A living faith, combined with good works, is required, and God supplies the faith of Christ to endure trials.

Faith is the foundation of the Christian's warfare and of every aspect of Christian life, since God cannot be seen and is known through what He has caused to be written. Love is the goal, but faith supports it. Salvation is by grace through faith, and faith itself is God's gift (Ephesians 2:8), coming through hearing the gospel (Romans 10:17); response in works follows what God gives. The whole book of Hebrews aims to rebuild the conviction of believers who were drawing back under trial, as Israel in the wilderness failed to enter God's rest through unbelief. Hebrews 11:1 is best understood as inner conviction, being sure of what is hoped for and certain of what is unseen, and this conviction works hand in hand with endurance, the refusal to surrender. Faith must be living rather than dead. Dead faith is merely informed and may be highly intellectual, but it does not submit. Living faith hears, yields, and changes life to please God, working through love, which is keeping the commandments (Galatians 5:6; I John 5:3). The examples of Hebrews 11 refute the idea that works are unnecessary, since Ephesians 2:10 says believers are created for good works. Abel illustrates this: he believed God's instruction and offered by faith in the coming sacrifice of Christ, the only adequate covering for sin.

Outside of God's grace and Christ's blood, not even love is as important as faith, because faith is our response to God's love. Without faith it is impossible to please God (Hebrews 11:6). Abel's acceptable sacrifice, Enoch's walk with God, and Noah's ark all came by faith, and a person is justified by faith in Christ's blood and saved by grace through faith, which is itself God's gift (Ephesians 2:8). Those in the flesh cannot please God because they lack the faith of Jesus Christ, but when God calls a person by name, that faith begins to grow and pleasing Him becomes possible. Abraham is the pattern: he went out not knowing where he was going, trusting God regardless. Trust is faith in action, the strongest evidence of belief, and it separates the truly converted from those who only believe intellectually. Faith shows itself in obedience, in separation from the world, and in denying self and following Christ, so the sanctified life proves whether one has the faith of Jesus Christ. The unconverted, lacking faith, compromise and rationalize, governed by carnal senses rather than trust in God's character. Faith is also needed to fight the Christian fight against the pull of the old way and to endure trials such as family opposition. Only those who humbly submit to God's will by faith, as Abraham did, will enter the Kingdom.

Faith is the foundation that supports and sustains the love of God, and it is what enables a believer to endure to the end amid trials, uncontrollable events, and unfulfilled promises. The patriarchs of Hebrews 11 served God for a century or more and died in faith without receiving the promises, yet they persevered because they were persuaded of God's promises and embraced them. To embrace means to draw something to oneself as a precious personal possession, not merely to believe it intellectually. Their conduct as strangers and pilgrims confessed that conviction. They did have doubts and lapses, like the father in Mark 9 who cried, "Lord, I believe; help my unbelief," but they kept going to the One who gives faith and who gives more of it. Faith is trust in a Being, not merely in a body of doctrine, and faith in what is said is only as strong as faith in the One who said it. Moses, Abraham, and the others knew their Creator, so His promises became as precious to them as He was. Such faith grows through diligently seeking God, praying, studying His word and works, and submitting to what is learned. It also rests on accepting that God is sovereign and that the timing of the promises is beyond human control. God has not called anyone to fail; faith can be lost, but it should never be.

Without faith it is impossible to please God (Hebrews 11:6), and the faith in view is not mere belief that God exists but a living, disciplined conviction that He rewards those who diligently seek Him, meaning those who search in order to become like Him. The decisive issue in questions such as the calendar is therefore faith in God's faithfulness, sovereignty, and providence, not technical calculations. God assigns responsibilities, and believers show faith by trusting that He oversees those He has assigned, by guarding and holding fast to what they received through the one He sent, and by submitting to His arrangements even when they seem flawed, as Jesus submitted to the Father's will and to civil authority. God's consistency of purpose, seen in Malachi 3:6 and Romans 11:29, makes Him trustworthy. Scripture repeatedly shows God sending prophets to call a degenerating people back to the "old paths" and away from doctrinal novelties. Faith is tested when God's commands seem to conflict with human reasoning or conscience. Abraham, offering Isaac, trusted that God could raise him from the dead and concluded that any defect lay in his own mind, not in God's command. The basic problem is that people do not think as God thinks, and faith is the means by which they come to think and live as He does. Faith comes by hearing the word of God delivered by one He has sent.

Faith is the highest priority in the Christian life because it is what God mainly intends to produce in the relationship with Him, and it motivates and sustains right action. Paul says to take the shield of faith "above all," and Hebrews teaches that without faith it is impossible to please God, that the just live by faith, and that endurance depends on confidence. Unbelief, not mere fleshly weakness, is the root of sin, as Adam and Eve and Israel in the wilderness show, and without faith there is no entrance into God's Family. Faith is a gift of God, but it must be perfected through use, as Abraham's life shows. Simple faith, like that of the blind men healed in Matthew 9, is not enough for the long, difficult trials that involve eternal stakes. Faith grows when a person obeys while recognizing that God owes nothing and that obedience is only duty. God then reveals Himself more clearly, making Him real. Faith is also built through three steps. Recognition is believing God and His works are real, though unseen, and this must go beyond the bare belief that even demons have. Evaluation is valuing God and His promises as precious, as a treasure for which one gladly gives up all. Action is the persistent works that complete faith. The same principles of valuing a goal and committing to it apply to physical health.

Real faith is not abstract belief or mere assent to facts about God. Pagans display zealous religious faith, even sacrificing children, but it is a human faith directed at idols and demons (I Corinthians 8, 10). True faith is an operation of God, an energy given through His Spirit that lets believers see Him as Creator, Father, Savior, and High Priest, and respond wholeheartedly to His Word. Its object is a living, loving Personality, not merely doctrines. Peter sank when he looked away from Christ, and Martha was turned from a cold fact about the resurrection to the One who is the resurrection. Biblical faith is best understood as trust, joined with warm conviction and emotional attachment. Faith's importance is seen in several ways. Salvation comes by grace through faith (Ephesians 2:8), and believers stay saved by living by faith. Without faith it is impossible to please God (Hebrews 11:6). Faith clears the way to the throne of grace, so prayer grows out of faith and has no existence apart from it. Faith also makes prayer strong and patient. Unbelief is the opposite danger: a heart controlled by it breaks trust and leads to falling away from the living God, the supreme disaster, because it thwarts His purpose of making believers like Him. Faith grows through Scripture, trials, prayer, and daily mutual exhortation in fellowship, and it matures into love.

Faith is the very purpose of everything God did through Christ. Citing John 6:29, "This is the work of God, that you believe on Him whom He has sent," the point is that all Christ said and did, up to and including the crucifixion and resurrection, was meant to produce faith. Its importance is shown by failure: Adam and Eve talked with God yet let their trust dissolve under Satan's deception, and Israel, though it witnessed plagues, the sea divided, and forty years of provision, fell short because the word preached was not mixed with faith (Hebrews 4:1-2). Like teenagers who believe their parents exist but not what they say, they thought they knew better than God. Faith itself is a gift coming through grace and justification (Ephesians 2:8), and believers live by "the faith of" the Son of God (Galatians 2:20). Yet it must be used. Faith without works is dead (James 2), so faith is perfected by obedience to God's Word rather than set against law. Faith does not nullify law but establishes it (Romans 3:31). The New Covenant creates the circumstances in which faith is strengthened so that salvation is achieved. God supplies the faith and help, but the believer must exercise it in the struggle between flesh and Spirit, choosing perfection over Gehenna.

Faith is the foundation of the Christian's preparation to overcome in the coming tribulation, and it is the first of three eternal virtues, faith, hope, and love, that Paul links in 1 Corinthians 13:13. Unlike prophecies, tongues, and knowledge, which fade when their usefulness ends, these three last forever. They stand or fall together, and the apostles link them twelve times. Faith comes first because Satan has struck at belief in God's existence through evolution and humanism, which rest on the premise that God does not exist. Without God there can be no faith, and humanism leaves even those who know of God with a shallow, unfocused fear of Him and weak obedience. Ephesians 2:8 shows that salvation comes by grace through faith, so without faith no one can reach God, who gives eternal life as a gift. Hebrews 11:1 does not define faith but says what it does. The Greek hupostasis, "a standing under," means faith is the foundation that supports conduct and gives conviction and certainty. Hope and love are built on it. Believing that God exists and believes what He says produces the hope that motivates us and the love toward God and one another that He commands. Those who overcome do so because they have faith, hope, and love.

Faith is central to God's purpose because conversion means exchanging the death-producing values absorbed from family, tradition, and culture for God's eternal values, and the human heart, deceitful and committed to what it already holds dear, resists this change. In John 6, when the people ask what works they must do, Jesus answers that the work of God is to believe in the One He sent. That work is not preaching the gospel, which belongs to the church, but God's producing faith in His people. Jesus' words carry the values God wants impressed on character, so unless His words are believed, those values have no chance to become part of a person. Where values were once absorbed subconsciously in childhood, God now calls His children to consciously accept His values, compare themselves to Him, and sacrifice what they prize when it conflicts with Him, as the rich young ruler could not do. Those who do not believe His words will never change, while Peter confesses that Jesus has the words of eternal life. Faith, which comes by hearing God's Word, makes it possible, with the Holy Spirit, for these values to become part of a person. It is therefore the foundation of the relationship with God and the platform on which everything else in His purpose is built.
