To the man "whose talk is of oxen," whose whole life is absorbed in the study of material things, a purely spiritual manifestation comes as a surprise. His instinctive impulse is to deny its reality as a thing obviously impertinent to his understanding of life. But one whose life is based on spiritual postulates, who is, however feebly, attempting to shape life in accordance with spiritual principles, though he may never have attained anything that can be interpreted as a distinct revelation from God by vision or voice or otherwise, yet must he by the very basic assumptions of his life be ready to regard such manifestations of God as intelligible, and indeed to be expected. So far from regarding divine interventions in life as impossible, we shall regard the Christian life which has no experience of them as abnormal, as not having realised its inheritance. The degree and kind of such intervention in life will vary; but it is the fact of the intervention that is important: the mode in a special case will be determined by the needs of that case. As we think along these lines we reach the conclusion that what we call the supernatural is not the unnatural or the abnormal, but is a higher mode of the natural. We are not surprised therefore to find that those whose spiritual development was such as to make it possible for God to choose them to fulfil special offices in relation to the Incarnation; who could be chosen to be, in the one case, the Mother of God-incarnate, and in the other, to be the guardian of the divine Child and His Blessed Mother, have the divine will in regard to the details of the trust committed to them, imparted to them in vision and in dream. So far from such vision and dream suggesting to us "a mythical element" in the Gospel narratives, they rather confirm our faith in that they harmonize with our instinctive conclusions as to what would be natural under the circumstances. We are prepared to be told that at this crisis in the Holy Child's life "the angel of the Lord appeareth to Joseph in a dream, saying, Arise, and take the young child and his mother, and flee into Egypt, and be thou there until I bring thee word; for Herod will seek the young child to destroy him. When he arose, he took the young child and his mother by night, and departed into Egypt." Thus early in our Lord's life is the element of tragedy introduced. The Incarnation of God stirs the diabolic powers, the rulers of "this darkness" to excited activity. The companion picture of the Nativity, of the Holy Child lying in Mary's arms, of the wondering shepherds, of the Magi from a far country,--the shadow of all this idyllic beauty is the massacre of the Innocents, the wailing of Rachel for her children. It is, as it were, the opening of a new stage in the world-old conflict where the powers of evil appear to have the advantage and can show the bodies of murdered infants as the trophies of their victory.
