14 He shall glorify me: for he shall receive of mine, and shall shew it unto you. 15 All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you. (John 16:14-15 KJV)
William Burkitt’s Commentary
Here Christ shews the advantage which would redound to himself by the coming of the Comforter; he declares that the Spirit should glorify him by his testimony, gifts, and miracles, and shall in all things accord with him, and thereby evidence that he hath his mission from him: He shall receive of mine, and shall shew it unto you. And, all things that the Father hath are mine.
Hence learn, that, although the union in essence amongst the persons in the Trinity is the same, yet the order of their subsistence and operation is distinct: the Son being from the Father, and the Holy Ghost from the Father and the Son; For all things that the Father hath are mine; And the Spirit shall take of mine, and shall shew it unto you.
Observe farther, that these words afford a strong argument to prove the divinity of Christ: All things which my Father hath are mine. Where Christ challenges to himself the incommunicable attributes of God, and consequently that essence which is inseparable from them.
Doth the Father know the secrets of all hearts? So doth Christ, All the churches shall know that I am he that searcheth the reins and hearts. Revelation 2:23
Is the Father eternal? So is Christ, I was set up from everlasting, &c. Proverbs 8:23
