“I will praise thee, O Lord, among the peoples; I will sing unto thee among the nations” (Psalm 57:11).
A heart that is not awakened to God will cause spiritual drowsiness, but awakened to God will create excitement and praise. There is nothing more boring than a heart that is sleepy toward our great God.
David points to his own heart and says, “My heart is fixed, O God, my heart is fixed; I will sing and and give praise.” What is fixed? The heart, the conscience, the will, the affections which draws the mind afterwards.
While we sleep God is working for us. When David awoke he wanted to tell the whole world what God had done for Him. God answers prayer, and whatever He does is for your good and His glory.
