Sometimes we do things we regret. That was certainly the case for David before he wrote Psalm 86. In II Samuel 11 we read about David’s regrets…mistakes…sins—adultery, deception and conspiracy to murder. That’s a lot to feel bad about. So, when in Psalm 86:11 David prays that the Lord would teach him how to live, it is an earnest prayer. He wants to be wholeheartedly committed to God. The King James Version uses the term “unite my heart”. In the New International Version, David prays for an “undivided heart”. He realizes that if his heart isn’t entirely focused on God, he will go down the wrong path, but he also sees that he needs God’s help to do it. He knows that what is impossible for humans is possible for God. (Luke 18:27)
His vow, in Psalm 86:12, to praise God forevermore, is also sincere. His reason is shown in Psalm 86:13. David knows that what he has done is deserving of death, but God in His great mercy has forgiven him. God is deserving of our praise simply because He is God, but His love and mercy toward David provided so much more motivation. David vowed not only to praise God, but to do it with enthusiasm, and to do it forever.
It is likely that most of the people reading this have not sinned to the same degree that David did in the case of Bathsheba and Uriah. But even the most noble among us are dependent on God’s grace to save us. We cannot save ourselves. (Ephesians 2:4-9) God wants us all to be completely devoted to Him. He wants us to ask for His help to live the way we should. He is ready and willing to give it, along with His grace, mercy, love and forgiveness. He has provided His Word so that we can learn more about His ways, but it takes commitment. We need to choose each day to put Him first, to praise Him and to give Him the glory.
David is one of my favourite characters in the Bible. The fact that he was a man after God's own heart despite the fact that he committed a lot of moral sins, is reassuring.
Exactly Rowena! He wasn't considered a man after God's own heart because he was perfect, but because he wanted to give God the glory. He didn't always succeed at doing the right thing, but he never gave up.
