How do we know the exclusivity of salvation through Jesus is true?

The exclusivity of salvation through Jesus is rooted in several key biblical passages. In Acts 4:12, Peter declares to the religious council that there is no other name under heaven given among men whereby we must be saved, affirming that Jesus is the sole means of redemption. This is reinforced by Jesus Himself, who proclaimed in John 14:6 that He is the way, the truth, and the life, stating emphatically that no one comes to the Father except through Him. The consistent testimony of the New Testament points to Jesus as the only mediator, underscoring that true faith and relationship with God can only be found through Him.
