Salvation is affirmed as being through faith in Christ alone, as seen in Paul’s use of Abraham as an example (Romans 4:13).
Salvation through faith is a foundational doctrine in Christian theology and is thoroughly supported in Scripture, particularly in Romans 4. Paul uses Abraham to demonstrate that God's promise of salvation was given before the law existed, thus emphasizing that the promise was based on faith and not on law-keeping (Romans 4:13-16). If salvation were through the law, as Paul points out, faith would be nullified and the promise made of no effect. Salvation rests entirely upon God's grace through faith in Christ, thus establishing the law only through that faith. It is not based on human effort but rather on God's work through His Son.
