7:18-29 On the positive side, David prays quite often, this time not asking for anything or complaining, but praising God for what God has already done. Prayer is David’s greatest strength!
11-12 David also had deep flaws: He committed adultery and murder! Yet, he repented! (Read Psalm 51, attributed to David, regarding his sorrow and guilt regarding the Bathsheba affair.) No sin is beyond God’s forgiveness if confessed!
Though flawed, David’s devotion to the Lord is what sets him apart from Saul and many others. 12:21 David “went to the house of the Lord and worshipped” right after learning that his son had died!
13-15:12 David failed miserably in passing down faith and morals to his children. He played favorites and did not discipline his children.
