Once David convinced King Saul that he was willing to fight the giant Goliath, Saul dressed him in a suit of armor and gave him his own sword. Although Saul was well meaning, David realized it would never work. “‘I cannot go in these,’ he said to Saul, ‘because I am not used to them.’ So he took them off. Then he took his staff in his hand, chose five smooth stones from the stream, put them in the pouch of his shepherd’s bag and, with his sling in his hand, approached the Philistine” (1 Samuel 17:39-40 NIV).
