We say what if I try God and fail. We think what if I don't have what it takes. God is always progressive. God is asking us to do stuff and we're scared it won't work. By the time we think we arrive, God gives us something new to do. If God gave us the end of the destination, it would scare us to the point we wouldn't want to do it. We may fail but we can point people to the one that doesn't fail. God is bigger than all your fears. If God tells you to do it, God will bring you through it. You can't lose as long as you're in Christ. Link
