Fathers !

Robin over on Robbieducky as he engages in parent ministry sets out a challenge for fathers. He points out that David was an awful father.
My question how could he fall into that way ? Perhaps where he was at with his sins, I wonder if he felt that he didn't have the moral authority that was his to discipline his son ?
If such a person who was after God's own heart be in that situation, we need God sooooooo much to help us guard our hearts and minds to these dangers. And of course to bring healing and restoration to us fathers, so we can be more like the father he would have us be.
