What do you do when you believe God is asking you to do something?

If you're like Moses, you have a million reasons why God should pick someone else. After all, you haven't been faithful, you really don't read your Bible like you should - and hey, isn't God aware of all those thing you did back then?

But what if all those reasons we come up with are really a smoke screen, so that we can hide behind our fears. So that God will leave us alone?

And what if those fears and reasons are the VERY THING keeping us from experiencing God's best?
