What role did Abraham play in the doctrine of salvation?

Abraham is often referred to as the father of faith, as he exemplified the principle of justification by faith in the Old Testament. Paul uses Abraham's example to demonstrate that righteousness comes through faith, predating the law and works, which means that his experience is not limited to the Jewish people but extends to all believers. Abraham believed God's promises, and this faith was counted as righteousness (Romans 4:3). Thus, for Christians, Abraham symbolizes the assurance that faith in God’s promises leads to salvation, illustrating that God’s method of saving His elect transcends time and cultural boundaries.
