For those who might not be familiar with David's story he was chosen as a young man to be the King of Israel. But first he proved himself worthy through multiple trials and challenges. He slay the champion of one of Israel's mightiest enemies, Goliath the giant. He served faithfully under King Saul despite Saul's manic mood swings and even Saul's attempts at ending David's life. He wrote just under half of the Psalm's in the Bible. He also killed a man, Uriah the Hittite, to obtain that man's wife. He lived in non-repentance for that sin for at least a year, then expressed disbelief when confronted with his sin by Nathan the prophet. His family situation was a mess, with one of his children attempting to kill him and take his throne. One of his wife's despised his walk with God, and one of his children raped his half-sister. One of his son's killed his own brother. And yet the Bible tells us that David took no action. (To learn more about this account read 2nd Samuel 13 and beyond) His family leadership was passive at best, destructive at worst.
Like all of us, David was human.
But what made him a man after God's own heart?
