Jesus says straightforwardly that the work of God is to believe in Him whom He sent. God's efforts are engaged in getting us to believe in Jesus, but believing in Him is far more than accepting that He died for the forgiveness of our sins. It is believing what He said for our instruction and what He lived as an example to us. It is following Him, imitating Him, obeying Him, and becoming more and more like Him every day. God is seeking men and women to worship Him in spirit and truth, and these are the ones who really believe.

Believing stands as an indispensable requirement for pleasing God and entering His Kingdom. Without confidence in His existence, fidelity, trustworthiness, wisdom, and promises, no one can please Him, for the one who approaches God must believe that He is and that He rewards those who diligently seek Him. This belief is not a mere academic acknowledgment but an active persuasion that moves a person to obey His laws, statutes, judgments, and commandments, producing approval by God and drawing the believer closer to Him. It encompasses trust in the fullness of what God has revealed about Himself, His Kingdom, eternal life, and the future inclusion of the faithful in the God Family. Such belief forms the solid foundation on which spiritual life rests, comparable to the subflooring of a house. It supplies the substance of things hoped for and the evidence of things not seen, imparting reality to the unseen Kingdom and prompting conduct aligned with God's Word. When this foundation is present, the believer stands firm amid trials; when absent, even hearing God's sayings proves insufficient, and the house built on sand collapses under pressure. Jesus Christ Himself exemplified this belief by humbling Himself, learning obedience through suffering, and remaining faithful to the point of death on the cross, thereby becoming the author of eternal salvation to all who obey Him. In an environment where credibility is widely doubted and end-time conditions will shatter normal life, God still requires His elect to maintain belief. The danger lies not in any failure on God's part but in the possibility that trials may erode human faith. Those who continue believing receive righteousness imputed to them, are counted as friends of God, escape condemnation, inherit everlasting life, and will not be put to shame at Christ's return. Conversely, those who do not believe remain condemned and cannot see life. Belief therefore demands protection through consistent prayer, study, obedience, and careful association with those who strengthen rather than undermine it, ensuring that the elect persevere to the saving of the soul.
