Speaking to King Saul, Prophet Samuel said, "You have done foolishly. You have not kept the Commandment of the Lord your God, which He commanded you. For now the Lord would have established your kingdom over Israel forever. But now your kingdom shall not continue. The Lord has sought for Himself a man after His Own Heart, and the Lord has commanded him to be commander over His people, because you have not kept what the Lord commanded you" (1 Sam. 13:13-14). You are going to read and study the life and ministry of David, the man after God's Own Heart in this book.
