An encouragement to pray

David has announced his conclusion and offered the illustration of his own experience concerning the forgiveness of God and the joy that follows. Now he presses home his applications. The first is an encouragement to pray. David's experience gives others a reason to pray; they are to do so in any season of need; they find in the Lord a place to hide; and, he brings them into an atmosphere of praise. If this is true of the godly who sin against the Lord, then there is hope for all who call upon his name.
