If New Testament Christianity is to reappear today with its power and joy and courage, men must recapture the basic conviction that this is a Visited planet. It is not enough to express formal belief in the "Incarnation" or in the "Divinity of. Christ"; the staggering truth must be accepted afresh -- that in this vast, mysterious universe, of which we are an almost infinitesimal part, the great Mystery, Whom we call God, has visited our planet in Person. It is from this conviction that there springs unconquerable certainty and unquenchable faith and hope. It is not enough to believe theoretically that Jesus was both God and Man; not enough to admire, respect, and even worship Him; it is not even enough to try to follow Him. The reason for the insufficiency of these things is that the modern intelligent mind, which has had its horizons widened in dozens of different ways, has got to be shocked afresh by the audacious central Fact -- that, as a sober matter of history, God became one of us.
