What does the Bible say about the grace of God in salvation?

Scripture reveals that salvation is entirely the work of God, showing no regard for human effort or decision. In Acts 7, we see Stephen's reference to God's dealings with Abraham, emphasizing that God took Abraham from idolatry, not because of Abraham's worthiness, but solely by His sovereign grace (Genesis 12:1). This unmerited favor is further reflected in passages like Ephesians 2:8-9, which state that we are saved by grace through faith, and this not of ourselves; it is the gift of God.
