there are two substances, God and Man; but one Person, that the Trinity may remain, and that there be not a quaternity introduced by the addition of the human3899 nature. How then can it be that God should not have mercy upon us, for whose sake God was made Man? 500 Much is that which He hath done already; more wonderful is that which He hath done, than what He hath promised; and by that which He hath done, ought we to believe what He hath promised. For that which He hath done, we should scarcely believe, unless we also saw it. Where do we see it? In the peoples that believe, in the multitude that has been brought unto Him. For that hath been fulfilled which was promised to Abraham;3900 and from these things which we see, we believe what we do not see. Abraham was one single man, and to him was it said, “In thy seed shall all nations be blessed.” If he had looked to himself, when would he have believed? He was one single man, and was now old; and he had a barren wife, and one who was so far advanced in age, that she could not conceive, even though she had not been barren. There was nothing at all from which any hope could be drawn. But he looked to Him That gave the promise, and believed what he did not see. Lo, what he believed, we see. Therefore from these things which we see, we ought to believe what we see not. He begat Isaac, we saw it not; and Isaac begat Jacob, and this we did not see; and Jacob begat twelve sons, and them we saw not; and his twelve sons begat the people of Israel; this great people we see. I have now begun to mention those things which we do see. Of the people of Israel was born the Virgin Mary, and she gave birth to Christ; and, lo, in Christ all nations are blessed. What more true? more certain? more plain? Together with me, long after the world to come, ye who have been gathered together out of the nations. In this world hath God fulfilled His promise concerning the seed of Abraham. How shall He not give us His eternal promises, whom He hath made to be Abraham’s seed? For this the Apostle saith: “But if ye be Christ’s” (they are the Apostle’s words), “then are ye Abraham’s seed.” 3901 4. We have begun to be some great thing; let no man despise himself: we were once nothing; but we are something. We have said unto the Lord, “Remember that we are dust;”3902 but out of the dust He made man, and to dust He gave life, and in Christ our Lord hath He already brought this same dust to the Kingdom of Heaven. For from this dust took He flesh, from this took earth, and hath raised earth to heaven, He who made heaven and earth. If then these two new things, not yet done, were set before us, and it were asked of us, “Which is the most wonderful, that He who is God should be made Man, or he who is man should be made a man of God? which is the more wonderful? which the more difficult?” What hath Christ promised us? That which as yet we see not; that is, that we should be His 3899 Homine. Vid. Serm. xvii. (lxvii. Ben.) 7 (iv.), note. 3900 Gen. xii. 3. 3901 Gal. iii. 29. 3902 Ps. cii. 14, Sept. (ciii.
