" When Jesus tells us that “apart from me you can do nothing” (John 15:5), he is inviting us into his life of a living dependence on his heavenly Father. When Jesus tells us to believe, he isn’t asking us to work up some spiritual energy. He is telling us to realize that, like him, we don’t have the resources to do life. When you know that you (like Jesus) can’t do life on your own, then prayer makes complete sense. "
