The point of 1 Corinthians 13 is that love is not our duty; it is our destiny. It is the language Jesus spoke, and we are called to speak it so that we can converse with him. It is the food they eat in God's new world, and we must acquire the taste for it here and now. It is the music God has written for all his creatures to sing, and we are called to learn it and practice it now so as to be ready when the conductor brings down his baton. It is the resurrection life, and the resurrected Jesus calls us to begin living it with him and for him right now. Love is at the very heart of the surprise of hope; people who truly hope as the resurrection encourages us to hope will be people enabled to love in a new way. Conversely, people who are living by this rule of love will be people who are learning more deeply how to hope.
