Every Christian would agree that a man’s spiritual health is exactly proportional to his love for God. But man’s love for God, from the very nature of the case, must always be very largely, and must often be entirely, a Need-love. This is obvious when we implore forgiveness for our sins or support in our tribulations. But in the long run it is perhaps even more apparent in our growing—for it ought to be growing—awareness that our whole being by its very nature is one vast need; incomplete, preparatory, empty yet cluttered, crying out for Him who can untie things that are now knotted together and tie up things that are still dangling loose.

C.S. Lewis
