David said to the Philistine, "You come against me with sword and spear and javelin, but I come against you in the name of the Lord Almighty, the God of the Armies of Israel, whom you have defied. This day the Lord will deliver you into my hands, and I'll strike you down and cut off your head. This very day I will give the carcasses of the Philistine army to the birds and the wild animals, and the whole world will know that there is a God in Israel. All those gathered here will know that it not by sword or spear that the Lord saves; for the battle is the Lord's, and he will give all of you into our hands." The Story
Even though I've read the story of David many times, this morning when I read it, I was struck by his words. David was able to prophecy! He told Goliath what God was going to do.
Goliath was the big huge enemy of Israel. They were terrified of him. But, David knew that God was bigger, so he was able to walk up to Goliath and simply say to him, "the Lord will deliver you into my hands."
This is true for me, and for you, too. God is greater. The Lord Almighty will deliver his children from the enemy that comes against them, and the whole world will know that He is God!
