So it was, when the Philistine arose and came and drew near to meet David, that David hurried and ran toward the army to meet the Philistine. Then David put his hand in his bag and took out a stone; and he slung it and struck the Philistine in his forehead, so that the stone sank into his forehead, and he fell on his face to the earth. So David prevailed over the Philistine with a sling and a stone, and struck the Philistine and killed him. But there was no sword in the hand of David.
1 Samuel 17:48-50 (NKJV)
Biblical Truth: Do not be afraid of the arrogant that ridicule you because of your faith, but have confidence in the promptings of the spirit. By divine guidance and determination fear is slayed.
