"The 'Resurrection' to which they bore witness was, in fact, not the action of rising from the dead but the state of having risen; a state, as they held, attested by intermittent meetings during a limited period (except for the special, and in some ways different, meeting vouchsafed to St. Paul). This termination of the period is important, for, as we shall see, there is no possibility of isolating the doctrine of the Resurrection from that of the Ascension.
"The next point to notice is that the Resurrection was not regarded simply or chiefly as evidence for the immortality of the soul. It is, of course, often so regarded today. I have heard a man maintain that 'the importance of the Resurrection is that it proves survival.' Such a view cannot at any point be reconciled with the language of the New Testament. On such a view Christ would simply have done what all men do when they die: the only novelty would have been that in His case we were allowed to see it happening. But there is not in Scripture the faintest suggestion that the Resurrection was new evidence for something that had in fact been always happening. The New Testament writers speak as if Christ's achievement in rising from the dead was the first event of its kind in the whole history of the universe. He is the 'first fruits,' the 'pioneer of life.' He has forced open a door that has been locked since the death of the first man. He has met, fought, and beaten the King of Death. Everything is different because He has done so. This is the beginning of the New Creation: a new chapter in cosmic history has opened." C. S. Lewis, Miracles
