Through everything in David's life, God kept David close to His heart, He gave David the tools of worship so that no matter where he was pushed by life, he would remain close to the Father. Although we don't understand we can trust in God. God is not lazy or forgetful or uninterested in your life. He has not just one, but both of His hands on your life! 

God is keeping us near to the promise even if He takes us away from the parts of the promise we understand, He always keeps us near to His heart.
