David's story of beating the giant Goliath is one of the most popular stories in the Bible. Allow me to show you the significance of David choosing to use the slingshot rather than the sword that Saul was giving him to beat Goliath. Here's that part in the Bible:1 Samuel 17
37 David said "The LORD who saved me from the claws of the lion and the bear will save me from this Philistine!" Saul finally consented. "All right, go ahead," he said. "And may the LORD be with you!"
38 Then Saul gave his own armor--a bronze helmet and a coat of mail.
39 David put it on, strapped the sword over it, and took a step or two to see what it was like, for he had never worn such things before. "I can't go in these," he protested. "I'm not used to them." So he took them off again.
40 He picked up five smooth stones from a stream and put them in his shepherd's bag. Then, armed only with his shepherd's staff and sling, he started across to fight Goliath.
And of course we all know what happened. During that time the sword was one of the best weapon plus the armor, helmet and the coat of mail for defense. This was what they thought David would need to beat Goliath. David who was never used to wearing these for fighting lions to protect the sheeps, chose to bring with him his staff and a sling.
What's the point here? Each one of us might be facing challenges in life and we are used to choosing the best approach of some people. Not knowing that sometimes the best approach for others might not be the best approach for us. In David's case, the sword might have been one of the best or maybe the most popular weapon of his time but for him it wasn't. In the same way with us.
What is your slingshot then?
I suggest that you read the whole story of David beating Goliath and you'll also learn that it was more than just his slingshot. It was more of who God is in his life.
