What does it mean to believe in Jesus?

To believe in Jesus encompasses a full reliance on Him as the source of spiritual and eternal life. John 3:16 asserts that 'whoever believes in him should not perish but have eternal life,' indicating the necessity of faith in Christ for salvation. This belief is not merely intellectual assent; it is about casting the entirety of one's soul upon Him, recognizing that salvation comes solely through His completed work. In John 14:6, Jesus said, 'I am the way, and the truth, and the life,' which highlights the exclusivity of Christ as the means to experience spiritual life. Furthermore, belief involves trusting in His righteousness and not one's own merits, which aligns with the overarching theme of grace in salvation.
