Why we Work

"As we have already seen and shall pick up again later, all this relates directly to what Paul says in I Corinthians 15:58: the resurrection means that what you do in the present, in working hard for the gospel, is not wasted. It is not in vain. It will be completed, will have its fulfillment, in God's future." N.T. Wright, Surprised by Hope, p. 162.
