How does Abraham's story relate to God's sovereignty?

The account of Abraham illustrates the profound sovereignty of God in selecting and justifying individuals. God called Abraham from a background of idolatry, demonstrating that He operates according to His will and purpose, irrespective of human merit. Abraham's life serves as a testimony to God's grace and power in transforming sinners into friends and heirs of the promise. Furthermore, Romans 4 underlines that God initiates this relationship by His sovereign choice, illustrating that salvation is entirely a work of divine grace.
