i found this and really liked it, I find myself so willing to make excuses for why God can't or won't use me. Whether or not we ask him to God is going to use us to bring glory to his name we are his children. it is when we can admit to being his and see him using us as a joy that we can fully step into the blessing he has for us.  

Jacob was a cheater, Peter had a temper, David had an affair, Noah got drunk, Jonah ran from God, Paul was a murderer, Gideon was insecure, Miriam was a gossiper, Rahab was a harlot, Martha 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.... Now, what's your excuse? Can God use you or not? God doesn't call the qualified, He qualifies the CALLED!!
