Did David forget? (2 Samuel 19-21)

Did David forget what happened on the day Samuel anointed him to be king?  Did he forget that great day when he killed Goliath with a simple sling and a stone?  Did he lose sight of the victories that the Lord brought him; victories that were not of his own strength?  Did David fail to remember that when he offered to build a house for God he was told that God would build a house for him?  How far had David come?  How much had he seen?  How could he forget it all at the simple threat brought on by his son?  Downtrodden and demoralized, David had nowhere to turn.  Thank goodness for a friend and supporter who spoke truth into his life at his greatest time of need.  Had it not been for Joab, David would have been completely defeated.  This spiritual giant had been whittled down to a fearful coward.  But Joab reminded him.  We need honest people in our lives, too.  We need people who are willing to challenge us and speak truth to us not matter what the personal consequence.  We need to be willing to listen to those people and to welcome them with open arms.  Without such a person, King David would surely have seen defeat.  We would be wise to surround ourselves with honest people like Joab who love us enough to tell us the truth when we need it the most.
