Beliefs are revealed best by the way we live our lives and not the way we speak them to everyone else. You want to tell people you are a Christian? Encourage your coworker instead of talking about him behind his back. You want to pray for the weak and poor on a mission trip? Then first start by praying for and not cursing the lady in traffic that accidental pulled out in front of you. You want to start up a ministry? Good, God wants you to begin one as well. Your ministry begins the moment you wake up and ends the moment you meet The Lord. God is not going to entrust you with the depths of the ocean if you refuse to leave the shallow end of your life.
