Introduction:
Abraham, originally named Abram, is a central figure in the Bible, revered as the patriarch of the Israelites, Ishmaelites, Edomites, and Midianites. His life and faith journey are pivotal in understanding the concept of justification by faith, a foundational doctrine in Christian theology. This entry explores the biblical narrative and theological implications of Abraham's justification by faith, primarily drawing from the Berean Standard Bible .

Biblical Narrative:
The account of Abraham's justification by faith is primarily found in the Book of Genesis and is expounded upon in the New Testament, particularly in the writings of Paul. The key event occurs in Genesis 15:6, where it is written, "Abram believed the LORD, and it was credited to him as righteousness" . This moment marks a significant turning point in biblical history, as it establishes the principle that faith, rather than works, is the basis for righteousness before God.

Genesis Account:
In Genesis 12, God calls Abram to leave his homeland and promises to make him a great nation. Despite his advanced age and the barrenness of his wife Sarai, Abram obeys God's call. The promise is reiterated in Genesis 15, where God assures Abram that his descendants will be as numerous as the stars. Abram's belief in this promise is what God credits to him as righteousness.

New Testament Exposition:
The Apostle Paul elaborates on Abraham's justification by faith in his epistles, particularly in Romans and Galatians. In Romans 4:3, Paul cites Genesis 15:6, emphasizing that Abraham's righteousness was credited to him because of his faith, not his works. Paul argues that this principle applies to all believers, both Jew and Gentile, stating, "Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all" (Romans 4:16).

In Galatians 3:6-9, Paul again references Abraham, asserting that those who have faith are children of Abraham and are blessed along with him. He writes, "So also, 'Abraham believed God, and it was credited to him as righteousness.' Understand, then, that those who have faith are sons of Abraham" (Galatians 3:6-7).

Theological Implications:
Abraham's justification by faith is a cornerstone of Christian soteriology, illustrating that salvation is a gift from God, received through faith rather than earned by human effort. This doctrine underscores the continuity of God's plan of salvation from the Old Testament to the New Testament, highlighting the unity of Scripture in its message of grace.

Faith and Works:
While Abraham's faith is credited as righteousness, his life also demonstrates the relationship between faith and works. James 2:21-24 discusses how Abraham's faith was made complete by his actions, particularly his willingness to sacrifice Isaac. James writes, "You see that his faith was working with his actions, and his faith was perfected by what he did" (James 2:22). This passage complements Paul's teachings by showing that genuine faith results in obedience and action.

Conclusion:
The account of Abraham's justification by faith serves as a profound example of trust in God's promises and the transformative power of faith. It lays the foundation for understanding the nature of righteousness and the means by which humanity can be reconciled to God. Through Abraham, the Bible presents a model of faith that transcends cultural and temporal boundaries, inviting all to partake in the blessings of faith.
