He raised up for them David as king, to whom also He gave testimony and said, "I have found David the son of Jesse, a man after My own heart, who will do all My will." (Acts 13:22)
There can be no greater testimony given than this: A man or woman after God's own heart. David was Israel's greatest king, a young shepherd who through obedience and a repentant heart rose to such prominence. I do not believe that God has stopped looking for such to give this testimony. God is not looking for perfection in man; He has already found that in His son. He is looking for a people who, like David, are willing to humble themselves and serve. God is looking for those who unashamedly worship Him, as David worshipped Him. He is looking for someone who is quick to confess his or her sin and turn from that sin, as David turned from his. He is not necessarily looking for a new king or great warrior. He is looking for an obedient shepherd who is willing to submit to authority and face life's giants. God is looking for a man after His own heart.
