“Let it never be forgotten that the virgin birth is an integral part of the New Testament witness about Christ, and that that witness is strongest when it is taken as it stands. We are not averse, indeed, to a certain logical order of apologetics; and in that order the virgin birth certainly does not come first. Before the virgin birth come the things for which testimony in the very nature of the case can be more abundant than for this. To those things no doubt the inquirer should be directed first, before he comes to consider this mystery which was first attested perhaps only by the mother of the Lord. But though that is true, though theoretically a man can believe in the resurrection, for example, without believing in the virgin birth, yet such a halfway conviction is not likely to endure. The New Testament presentation of Jesus is not an agglomeration, but an organism, and of that organism the virgin birth is an integral part. Remove the part, and the whole becomes harder and not easier to accept; the New Testament account of Jesus is most convincing when it is taken as a whole. Only one Jesus is presented in the Word of God; and that Jesus did not come into the world by ordinary generation, but was conceived in the womb of the virgin by the Holy Ghost.”
