Our friend shared with us a quote by Oswald Chambers. He said that when a person is truly born again they are condemned to a life of holiness. That is so true. "Be holy, for I am holy."
What grieves God? Our hearts that aren't even willing to live a holy life. The holy Spirit is grieved when we do not even strive to do it. David wasn't perfect. David was a man after God's own heart. Because of his heart and the attitude.
It really encouraged us to have this constant inevitable desire to live a life pleasing to God. It starts deep in heart. This is our prayer to have a heart that is pleasing to God, a heart full of enthusiasm of faith.
