At the burning bush, Moses received a huge assignment from God and he had some questions. He wondered how this was going to work. He asked the same kind of questions and offered up the same kind of excuses that you might be asking when God says He wants to do something great in your life. God may not speak to you the way He spoke to Moses, but you do need to recognize what God is calling you to and neutralize the excuses that keep you from pursuing that calling.
