1 Samuel 17:23 KJV — And as he talked with them, behold, there came up the champion, the Philistine of Gath, Goliath by name, out of the armies of the Philistines, and spake according to the same words: and David heard them.
What killed Goliath was the fact that his offensive words were heard by a Giant-killer.
Goliath had said the same words before on other occasions and nothing had happened to him.
But the moment a Giant-killer heard him, that became Goliath’s beginning of the end.
Will you let the Giant-killer inside you hear the words of the Goliaths around you?
