'The liberating fact is that the message we take to the frontiers is that people everywhere should seek their own best interest. We are summoning people to God. And those who come say, "In your presence there is fullness of joy; at your right hand are pleasures forevermore." (Ps. 16:11). God glorifies himself among the nations with the command, "Delight yourself in the LORD!"(Ps. 37:4). His first and greatest requirement of all men everywhere is that they repent from seeking their joy in other things and begin to see it only in him.'
John Piper, Let The Nations Be Glad, p.56.
