There is a reason why God said about David, "I have found a man after my own heart", David knew how to touch God's heart through praise and worship. During a period when the worship of God was more focused on the shedding of the blood of animals, David reach into realms no one had tasted before, he understood that what actually pleased God were not the blood sacrifices, but praise offered from a sincere heart, not necessarily perfect, but a sincere and genuine heart. No wonder he won so many battles, no wonder God tolerated his foolishness a times. Lesson, if you want to see God's power and blessing like never before, the secret is knowing and worshipping God in your secret place.
