And Samuel said to Saul, “You have done foolishly. You have not kept the command of the LORD your God, with which he commanded you. For then the LORD would have established your kingdom over Israel forever. But now your kingdom shall not continue. The LORD has sought out a man after his own heart, and the LORD has commanded him to be prince over his people, because you have not kept what the LORD commanded you.”
1 Samuel 13:13-14
But is is not as if He knew not where he was that God thus seeks Him a man, but, speaking through a man, He speaks as a man, and in this sense seeks us. For not only to God the Father, but also to His Only-begotten, who came to seek what was lost, we had been known already even so far as to be chosen in Him before the foundation of the world. “He will seek him,” therefore means, He will have His own.
Augustine City of God xvii.6
