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 time when there is nothing at all in your soul except a cry for help may be just that time when God can't give it: you are like the drowning man who can't be helped because he clutches and grabs. Perhaps your own reiterated cries deafen you to the voice you hoped to hear.
