Psalm 13 - What a great turnaround. I think anyone who has followed the Lord for any period of time has felt like David did at the beginning - "Lord! Where are You?!" But how quickly he turns around is remarkable! Two verses of despair, two verses of crying out, then all of a sudden he is trusting, rejoicing in his heart, and singing to the Lord!
What a comeback! Let's not take more than 4 verses to do the same!
