It happened, when the Philistine arose, and came and drew near to meet David, that David hurried, and ran toward the army to meet the Philistine.
"David lived by a very simple principle: nothing to prove, nothing to lose. He didn’t try to impress anybody in the army of Israel. He didn’t try to impress his brothers. He didn’t even try to impress God. He just ran to meet Goliath." [Note: Swindoll, p. 46.]
