What does the Bible say about God's call to Abraham?

In Acts 7:2-5, the God of glory appeared to Abraham while he was in Ur of the Chaldees and commanded him to 'get out' of his country and kindred. This call signifies not only physical relocation but also a divine summons to follow God's plan. Abraham was chosen by God's sovereign grace, which underscores the belief that salvation comes not from human merit but from God's initiative. His obedience illustrates how the call of God compels His chosen to respond in faith, leaving behind their former lives.
