David was the last one we would have chosen to fight the giant, but he was chosen of God.
Dwight L. Moody'Faith cometh by hearing and hearing by the Word of God' (Rom. 10:17). That is whence faith comes. It is not for me to sit down and wait for faith to come stealing over me with a strong sensation, but is for me to take God at His Word.
Dwight L. MoodyWhen the Spirit came to Moses, the plagues came upon Egypt, and he had power to destroy men's lives; when the Spirit came upon Elijah, fire came down from heaven; when the Spirit came upon Gideon, no man could stand before him; and when it came upon Joshua, he moved around the city of Jericho and the whole city fell into his hands; but when the Spirit came upon the Son of Man, He gave His life; He healed the broken-hearted.
