Why is belief in Jesus crucial for salvation?

Belief in Jesus is foundational to the Christian faith, as articulated in John 14:6, where Jesus claims, 'I am the way, the truth, and the life; no man cometh unto the Father, but by me.' This statement emphasizes that salvation is not achievable through human effort or religious deeds but solely through faith in Christ. The apostle Paul reinforces this in Acts 16:31, saying, 'Believe on the Lord Jesus Christ, and thou shalt be saved.' Salvation involves recognizing our sinfulness and need for a Savior, and God's grace enables us to believe, which is a gift from Him (Ephesians 2:8-9).
