What does the Bible say about the works of Abraham?

In John 8, Jesus made a clear distinction between true children of Abraham and those who merely claimed his lineage. He states that if they were truly Abraham's children, they would do the works of Abraham (John 8:39). This implies that genuine faith produces a likeness to Abraham in our actions—specifically, a life characterized by faith and obedience to God. Throughout Scripture, particularly in Genesis, we see Abraham’s actions reflecting his trust in God's promises, marking him as a model of faith for all believers.
