You remember the famous story of David and Goliath. I think there’s a lot we can learn from this story. David visited the battlefield, where the Israelites were fighting the Philistines—and frankly, they were doomed to lose because nobody would go up against Goliath the giant. David was appalled that they were intimidated by a giant, because after all, they were God’s people, and God would give them the victory.

Finally, King Saul sent for him because David had volunteered to fight Goliath. Of course, Saul was reluctant to let him do this, knowing it was highly unlikely David could. But David insisted and told Saul how he had killed a lion and a bear. He said, The Lord who rescued me from the paw of the lion and the paw of the bear will rescue me from the hand of this Philistine (1 Samuel 17:37).

Saul relented; after all, nobody else was willing to even try, and then Saul tried to tell David how to do it. “Here,” he said, “put on my armor, take my sword.” David immediately realized he couldn’t use Saul’s armor.

I cannot go in these, he said to Saul, because I am not used to them (1 Samuel 17:39).

He took them off, found his five smooth stones, got his slingshot in his hand, and faced Goliath. You know the story: He takes aim at Goliath’s head, hits him in the right place, and knocks him out. Then he cuts off Goliath’s head with his own sword, and claims victory.

How did David defeat Goliath? By using his slingshot. You don’t kill giants with slingshots—right? But that’s what David was good at; that’s how he had defeated the lion and the bear; that’s the gift God had given him. David was smart enough to realize trying to do what God wanted him to do in someone else’s armor would lead to disaster.

Now, think about some lessons we can learn from this. When you try to do your work to please people; when you try to copy others and do what they’re doing, it’s like putting on Saul’s armor—you can’t do it. But when God has given you a gift, skill, or opportunity, don’t underestimate God’s power in you, doing it the way he’s gifted you.

Use your slingshot. It may not be the conventional way to do things, but if that’s how God is leading you, don’t be intimidated by what others think. Go with what God has given you.
