How do we know that Jesus Christ is the only way to salvation?

The exclusivity of Christ as the only way to salvation is foundational to the Christian faith. In John 14:6, Jesus asserts, 'I am the way, the truth, and the life: no man cometh unto the Father, but by me.' This claim underscores that salvation is only through faith in Him, and affirming that He bore our sins on the cross demonstrates the completeness of His atoning sacrifice. Additionally, Acts 4:12 reiterates this truth, stating that there is no other name under heaven given among men, whereby we must be saved.
