How small-minded of us in our hopelessness to look at our closed Bible and say, "What I need is ____, and this is not in the Bible." How do we know we need _____ and not some utterly unexpected hope that the Bible will awaken in us when we read it in faith?
Indeed, we may lack hope because we think we need something we do not need. It may take the Word of God to show us what we really need, and then to give us the power to get it. In the end what we really need is Christ. He is the sum of all our hopes. . . . Sometimes what we need from the Bible is not the fulfillment of our dream, but the swallowing up of our failed dream in the all-satisfying glory of Christ. We do not always know the path of deepest joy. But all Scripture is inspired by God to take us there.
