1 Sam 13 & Acts 13(v22) say that David was a man after God’s heart. He was possibly the most passionate believer who ever lived. This psalm is written during one of the toughest times of David’s life. He has been anointed as King and promised the throne, yet the reigning authorities are hunting him down like a wild animal. He is amazingly grateful in spite of his circumstances. Verses 3-4 really tell us the story of his heart. No one in the New Testament ever captured the love of our Lord better than the Apostle John.
