Don't even think about it. This would be the worst mistake you could possibly make. Believe me, His arms are a lot longer than yours and He'll crush you everytime.
God uses ordinary people, like you and me, to do extraordinary things. He knows the talents and gifts that He has given each of us and He can move us into a situation so that we have to use them. A couple of my favorite things to tell my kids are, God does not call the qualified, He qualifies the called and I may not know what the future holds, but I know who holds the future. Don't you just love it!?!
He's looking for people who love Him and trust Him with all of their being. People who won't try and limit Him, but instead they realize how much He is capable of.
God tells us in His word that He knows the plans He has for us. Now get out of His way and let Him execute the plan.
