Charles Ellicott Commentary John 16:15

"All things whatsoever the Father hath are mine: therefore said I, that he taketh of mine, and shall declare [it] unto you." — John 16:15 (ASV)

All things that the Father hath are mine (John 16:15). He has told them that the Spirit’s work is to glorify Him, to receive of His, and announce to the world. The basis of this saying is in the fact that the Son is the Revealer of the Father, and that the fullness of the truth (John 16:13) is given to Him. The words appear from the context not to express the spiritual relation of the Son to the Father, but the fullness of the communication to Him in His human nature of the divine truth which He was to reveal to man (Compare to Notes on John 1:18; John 8:42; John 10:36; John 17:10; Matthew 11:27; Colossians 1:19; Colossians 2:2–3).

He shall take of mine, and shall shew it unto you (John 16:15). Better, He taketh of Mine, and shall declare it unto you. The present tense expresses the unchanging relation of the Spirit to the Son.

It should be noted that in these verses (John 16:14–15) there is an implication of the following doctrinal truths. They are implied, let us remember, in the words of our Lord Himself, and that they are implied and not stated increases the force of their meaning:

1. The divinity of the Son: He shall glorify Me (John 16:14); All things that the Father hath are Mine (John 16:15).
2. The personality of the Holy Spirit: He shall receive of Mine (John 16:14). The Greek word, ἐκεῖνος, expresses this in the most emphatic way. This word is used of the Holy Spirit in John 16:8; John 16:13, and in John 14:26; John 15:26.
3. The Trinity in Unity, and Unity in Trinity: “the Father;” “I;” “He.”
