1 Samuel 17:38-40 Then Saul dressed David in his own tunic. He put a coat of armor on him and a bronze helmet on his head. David fastened on his sword over the tunic and tried walking around, because he was not used to them.
“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.
As I read this scripture I thought how many times we try to be someone or something we are not. Maybe we try to "dress to impress," when really that is not who we are. Or we try to read up on something so we can be an "expert" when really we are just regurgitating the ideas and words of another.
I think whether we are doing this at the request of someone else - trying to fit into the mold they have made like Saul tried to have David do, or because of some fleshly desire of our own, it will never work.
We are uniquely designed to be the person God created us to be. When we try to put on something we are not, the burden becomes to heavy for us to bear because we weren't made for that. To often we try to make it a good fit, even though one size rarely fits all.
However, when we be who we are, we can succeed at what God designed us for no matter how impossible it seems. Just like David killing the giant with a small smooth stone.
