Jesus Christ, in addressing the crowd of 5,000 who followed Him for physical sustenance rather than spiritual truth, clarifies the essence of God's work. He instructs them, saying, "This is the work of God, that you believe in Him whom He sent." Despite witnessing His miracles, which served as signs of His identity, the people failed to grasp their spiritual significance, focusing instead on material benefits. Jesus emphasizes that true belief in Him goes beyond mere acknowledgment of His existence or deeds. It involves cleaving to, adhering to, trusting, relying on, and having faith in Him as God's Messenger. This deep belief is not universal or easily attained, as it requires being appointed by the Father to know both Him and His Son. Jesus further explains that only those drawn by the Father can come to Him, and He will not cast them out, promising to raise them up at the last day. This divine appointment to true belief marks them as the firstfruits of God's spiritual creation, distinct from the rest of the world who will not know God until a later time.

Christianity requires faith in God as He is revealed in Jesus Christ. This faith involves accepting the truth of our deep spiritual need and the work of the divine Christ, who provides the basis of our salvation from sin through His death. It also encompasses belief in Him and in the demonstration of the truth of His work and teachings through the resurrection. The world remains disbelieving unless God Himself brings faith out of non-faith, just as He brings life out of death or creation out of nothing. God not only creates and loves but also leads those who have fallen into sin to faith, producing in them what they could never achieve on their own. In the story of Jesus and Thomas, one week after the resurrection, Jesus appears to Thomas to lead him to faith. Thomas, initially a doubter, responds with the highest profession of belief, worshiping Him and declaring, My Lord and my God. Jesus does not excuse Thomas's unbelief but comes down to his level to help him through, saying, Do not be unbelieving, but be believing. The presence of Christ, identified by the wounds in His hands, feet, and side, ultimately convinces Thomas, revealing the love of Christ as the greatest proof. Christ provides what is needed for honest intellectual questions, showing that while reasoned arguments are important, it is His love demonstrated by His death that ultimately convinces. Jesus further speaks of a great blessing, saying, Blessed are those who have not seen and yet have believed. This blessing is not for a subjective faith without evidence but for a satisfied faith that rests on what God provides, not yearning for visions, miracles, or other experiences as proof of God's favor. Such faith, superior to one based on visible signs, is common to all who call upon the name of Christ as God and Savior. The Gospel of John emphasizes this faith in Jesus Christ, highlighting numerous blessings that flow from believing in Him, including becoming children of God, receiving eternal life, deliverance from judgment, spiritual satisfaction, and the promise of resurrection. Through faith, believers also see the glory of God, live a holy life, become fruitful, and receive the benefits of Christ's prayers on their behalf. The purpose of John's Gospel is to lead people to believe that Jesus is the Christ, the Son of God, and through that belief, to have life through His name. From first to last, it serves as a testimony to Jesus Christ, encouraging everyone to believe in Him and enjoy God's blessings.

The first qualification for a Christian minister is a belief in God, followed closely by the conviction that the Bible is God's authoritative Word, containing His instructions for living. However, not all churches adhere to this principle, as seen in the case of Gretta Vosper, a minister at West Hill United Church in Toronto, who openly declared her atheism. Despite her lack of belief in a supernatural, interventionist divine being, she retained her credentials and position within the United Church of Canada, a denomination known for its liberal stance. At West Hill United Church, traditional elements of worship have been altered: prayer has become community sharing time, hymns have been rewritten to exclude references to God and Jesus Christ, and discussions of Them have been replaced with themes of love, compassion, and beauty. Vosper's approach reflects a shift toward progressive and humanistic ideology, focusing on creating healthy, engaged communities rather than adhering to biblical teachings.

Believing in Jesus Christ is central to knowing the truth that unites and frees us from the deceptive teachings of the world. As Jesus taught in the Temple, He declared to those who believed in Him that continuing in His word would make them His disciples, enabling them to know the truth and be liberated from a destructive lifestyle. This truth, when lived, aligns us with God's way, fostering a desire to repent and improve our lives, bringing harmony, peace, and confidence as we emulate how He would live in our place. Jesus Christ has been made our wisdom, righteousness, sanctification, and redemption. Following Him provides us with a system of beliefs rooted in the laws of His Father, guiding us to live wisely and righteously. The call to believe in Him, as expressed to the prison keeper by Paul and Silas, implies an active movement toward the way Jesus lived, committing ourselves fully to His conduct and teachings. This belief is not merely acknowledgment but a transformative action that changes our direction in life. Jesus emphasized that He is the bread of life, the true sustenance from heaven that gives life to the world. Those who come to Him and believe in Him will never hunger or thirst, finding satisfaction in His doctrine and the atonement of His sacrifice, leading to a life directed toward eternal life. He clarified that believing in Him is the work of God, requiring right actions based on faith to prove its genuineness, a vital part of the sanctification process. Furthermore, Jesus taught that no one can come to Him unless drawn by the Father, highlighting the special calling required to truly believe. Those given to Him by the Father will not be cast out, and He will work with them to complete their calling, ensuring that none are lost but are raised up at the last day. Eternal life comes from knowing and believing in the only true God and Jesus Christ, whom He sent, a knowledge that encompasses living Their way of life through obedience to His commandments. Believing in Jesus Christ is essential for salvation, as He promised that whoever believes in Him will not perish but have everlasting life. This belief frees us from condemnation and passes us from death to life, allowing rivers of living water—righteousness, love, and self-control—to flow from our hearts. Through this belief, we are kept by the power of God, rejoicing even in trials, as it proves our faith and prepares us for the glory at His appearing. As a chosen people, we are called to love and believe in Jesus Christ, even without seeing Him, rejoicing with unspeakable joy as we strive for the salvation of our souls. We are to follow Him wherever He goes, adhering to His doctrine and actions without compromise, humbling ourselves in obedience to become like Him. Our citizenship is in heaven, and as we look for His return, we prepare by believing and following Him, confident that He who began a good work in us will complete it until the day of His coming.

Jesus Christ stands as the central figure of spiritual nourishment and life, as He declares in John 6:35, "I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst." His words emphasize that true satisfaction and eternal life are found only through a deep commitment to Him, a belief that goes beyond mere acknowledgment to a profound trust and assimilation of His teachings. He asserts in John 6:47, "Most assuredly, I say to you, He who believes in Me has everlasting life," highlighting that this belief results in the greatest blessing of all—eternal life. Jesus further illustrates this by stating in John 6:53-54, "Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day." He clarifies that this is not a literal act but a spiritual acceptance and assimilation of His sacrifice, which sustains spiritual life as physical food sustains the body. He reinforces in John 6:63, "It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life," underscoring that His teachings carry the essence of spiritual vitality. Belief in Jesus as the Messiah is presented as a work, a labor of faith, as He explains in John 6:29, "This is the work of God, that you believe in Him whom He has sent." This belief requires effort to assimilate His words, turning raw knowledge into conviction through meditation and application. Yet, Jesus also acknowledges in John 6:44, "No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day," indicating that this faith is a gift initiated by God's powerful drawing. He assures in John 6:37, "All that the Father gives Me will come to Me; and the one who comes to Me I will by no means cast out," promising to guard and preserve those given to Him, ensuring their salvation to the very end.
