God uses people that have been through something.

Jacob was a cheater, Peter had a tempter, David had an affair, Noah got drunk, Jonah ran from God, Paul was a murderer, Gideon was insecure, Miriam was a gossip, Mary was a worrier, Thomas was a doubter, Sara was impatient, Elijah was moody, Moses stuttered, Zaccheus was short, Abraham was old and Lazarus was dead. So whats your excuse now? God uses fallible humans that fall short. GOD can use you too!!
