For His Pleasure

It is God's pleasure to magnify the glory of His free & sovereign grace in choosing a people that they might be for Him "a name, a praise, and a glory (Jeremiah 13:11).

In other words, to extend the pleasure that God has in His own name, He calls out a people to enjoy and praise and proclaim that name. The Bible calls these people "the elect," "the chosen."

John Piper
