10. “If I do not the works of my Father, believe me not. But if I do, though ye will not believe me, believe the works; that ye may know and believe that the Father is in me, and I in Him.” The Son says not, “the Father is in me, and I in Him,” as men can say it. For if we think well, we are in God; and if we live well, God is in us: believers, by participating in His grace, and being illuminated by Himself, are in Him, and He in us. But not so is it with the only-begotten Son: He is in the Father, and the Father in Him; as one who is equal is in him whose equal he is. In short, we can sometimes say, We are in God, and God is in us; but can we say, I and God are one? Thou art in God, because God contains thee; God is in thee, because thou art become the temple of God: but because thou art in God, and God is in thee, canst thou say, He that seeth me seeth God; as the Only-begotten said, “He that hath seen me, hath seen the Father also;” and “I and the Father are one”? Recognize the prerogative of the Lord, and the privilege of the servant. The prerogative of the Lord is equality with the Father: the privilege of the servant is fellowship with the Saviour.
