Introduction To Christianity - Closing

Even the Christian may be assailed by the nightmares
induced by the fear of fruitlessness, out of which the
pre-Christian world created these moving images of the
anxiety that all human activity is vain. But his nightmare
is pierced by the saving, transforming voice of
reality: "Have courage, I have conquered the world"
(John 16.33). The new world, with the description of
which, in the image of the final Jerusalem, the Bible ends,
is no Utopia but certainty, which we advance to meet in faith.
A salvation of the world does exist - that is the confidence
which supports the Christian and which still makes it
rewarding even today to be a Christian.
