Hope is one of the Theological virtues. This means that a continual looking forward to the eternal world is not (as some modern people think) a form of escapism or wishful thinking, but one of the things a Christian is meant to do. It does not mean that we are to leave the present world as it is. If you read history you will find that the Christians who did most for the present world were just those who thought most of the next.

C. S. LewisThe real Oxford is a close corporation of jolly, untidy, lazy, good-for-nothing humorous old men, who have been electing their own successors ever since the world began and who intend to go on with it. They'll squeeze under the Revolution or leap over it when the time comes, don't you worry.
