John Piper, Desiring God, 1996, p. 156.
Prayer pursues joy in fellowship with Jesus and in the power to share His life with others. And prayer pursues God’s glory by treating Him as the inexhaustible reservoir of hope and help. In prayer we admit our poverty and God’s prosperity, our bankruptcy and His bounty, our misery and His mercy. Therefore, prayer highly exalts and glorifies God precisely by pursuing everything we long for in Him and not in ourselves.
