How do we know God's grace was upon Abraham?

Abraham was called by God to leave his homeland and family, reflecting God's merciful choice to guide him to Canaan, a land promised to him and his descendants. Acts 7:2-3 highlights that God spoke to Abraham while he was still in Ur, indicating that His initiative and grace preceded Abraham's actions. Furthermore, Abraham believed God, and this faith was counted as righteousness (Genesis 15:6), showcasing that it was God's grace that enabled Abraham to respond in faith and obedience. This demonstrates that salvation—and God's plans—are rooted in His mercy.
