The Virgin Birth, a Miracle

Sunday I will be preaching on...

"Why the Virgin Birth is Necessary"

and i won't have time to go into depth about Miracles in general.... so i will post some stuff this week.... Batting Leadoff, CS Lewis:
The Grand Miracle.
One is very often asked at present whether we could not have a Christianity stripped, or, as people who asked it say, 'freed' from its miraculous elements, a Christianity with the miraculous elements suppressed. Now, it seems to me that precisely the one religion in the world, or, at least the only one I know, with which you could not do that is Christianity. In a religion like Buddhism, if you took away the miracles attributed to Gautama Buddha in some very late sources, there would be no loss; in fact, the religion would get on very much better without them because in that case the miracles largely contradict the teaching. Or even in the case of a religion like Mohammedanism, nothing essential would be altered if you took away the miracles. You could have a great prophet preaching his dogmas without bringing in any miracles; they are only in the nature of a digression, or illuminated capitals. But you cannot possibly do that with Christianity, because the Christian story is precisely the story of one grand miracle, the Christian assertion being that what is beyond all space and time, what is uncreated, eternal, came into nature, into human nature, descended into His own universe, and rose again, bringing nature up with Him. It is precisely one great miracle. If you take that away there nothing specifically Christian left. There may be many admirable human things which Christianity shares with all other systems in the world, but there would be nothing specifically Christian. Conversely, once you have accepted that, then you will see that all other well-established Christian miracles--because, of course, there are ill-established Christian miracles; there are Christian legends just as much as there are heathen legends, or modern journalistic legends--you will see that all the well-established Christian miracles are part of it, that they all either prepare for, or exhibit, or result from the Incarnation. Just as every natural event exhibits the total character of the natural universe at a particular point and space of time; so every miracle exhibits the character of the Incarnation. Now, if one asks whether that central grand miracle in Christianity is itself probable or improbable, of course, quite clearly you cannot be applying Hume's kind of probability. You cannot mean a probability based on statistics according to which the more often a thing has happened, the more likely it is to happen again (the more often you get indigestion from eating a certain food, the more probable it is, if you eat it again, that you again have indigestion). Certainly the Incarnation cannot be probable in that sense. It is of its very nature to have happened only once. But then it is of the very nature of the history of this world to have happened only once; and if the Incarnation happened at all, it is the central chapter of that history. It is improbable in the same way in which the whole of nature is improbable, because it is only there once, and will happen only once. (God in the Dock pp. 80-82)
