How do we know that salvation is through Christ alone?

The foundation of our belief in salvation through Christ alone is rooted in the clear declarations of Scripture, particularly in Galatians 2:16 which emphasizes, 'A man is not justified by the works of the law, but by the faith of Jesus Christ.' This underscores that human efforts cannot achieve righteousness and that salvation is a gift from God through faith in Christ’s finished work. Moreover, Acts 4:12 states, 'Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.' Therefore, the exclusivity of Christ as the only mediator between God and man is affirmed, ensuring that belief in Him alone secures our eternal destiny in the presence of God.
