I. It is so, first of all, in the comparatively simple order of facts with which it deals. Nothing can be simpler or more comprehensive than our Lord's teaching. He knew what was in man. He knew, moreover, what was in God towards man as a living power of love, who had sent Him forth "to seek and save the lost;" and beyond these great facts, of a fallen life to be restored, and of a higher life of divine love and sacrifice, willing and able to restore and purify this fallen life, our Lord seldom traversed. Unceasingly He proclaimed the reality of a spiritual life in man, however obscured by sin, and the reality of a divine life above him, which had never forsaken him nor left him to perish in his sin. He held forth the need of man, and the grace and sacrifice of God on behalf of man. And within this double order of spiritual facts His teaching may be said to circulate. He dealt, in other words, with the great ideas of God and the soul, which can alone live in Him, however it may have sunk away from Him. These were to Him the realities of all life and all religion. There are those, I know, in our day, to whom these ideas are mere assumptions--"dogmas of a tremendous kind," to assume which is to assume everything. But with this order of thought we have in the meantime nothing to do. The questions of materialism are outside of Christianity altogether. They were nothing to Christ, whose whole thought moved in a higher sphere of personal love, embracing this lower world. The spiritual life was to Him the life of reality and fact; and so it is to all who live in Him and know in Him. The soul and God are, if you will, dogmas to science. They cannot well be anything else to a vision which is outside of them, and cannot from their very nature ever reach them. But within the religious sphere they are primary experiences, original and simple data from which all others come. And our present argument is, that Christ dealt almost exclusively with these broad and simple elements of religion, and that He believed the life of religion to rest within them. He spoke to men and women as having souls to be saved; and He spoke of Himself and of God as able and willing to save them. This was the "simplicity" that was in Him.
