What does the Bible say about God's calling and blessing?

In Isaiah 51, the Lord reminds us of His calling and blessing when He says, 'Listen to me, you who pursue righteousness.' This reflects God's personal and sovereign act of choosing individuals for salvation. Just as He called Abraham from a life of idolatry, He calls each of His chosen unto Himself. Abraham's call illustrates that it is the Lord who initiates salvation, declaring, 'I called him alone'—indicating that salvation is purely an act of God's grace, not a result of human effort. This principle applies to all believers; we are hewn from the rock of depravity and lifted from the pit of sin by God's sovereign will.
