How do we know that salvation comes only through Jesus Christ?

The exclusivity of salvation through Jesus Christ stems from the recognition that he fulfilled the requirements necessary for redemption. Romans 5:8 emphasizes how Christ died for our sins while we were still sinners. His death served as a substitute for the judgment we deserve, ensuring that those who believe in him are justified and free from condemnation. The theological framework of sovereign grace teaches that it is not by our works or righteousness that we achieve salvation, but solely through faith in Christ's completed work on the cross.
