Even the Spirit of truth. — Comp. John 15:26; John 16:13, and 1 John 5:6. He is called the Spirit of Truth, because part of His special office is to bring truth home to the hearts of men, to carry it from the material to the moral sphere, to make it something more than a collection of signs seen or heard — a living power in living men.
Whom the world cannot receive. — The Holy Spirit can be received only by those who have the spiritual faculty. It cannot be otherwise. The unbelieving world, caring only for things of the senses, has lost its spiritual perception. It has no eye to see and no heart to know spiritual things, for they are spiritually discerned. (Comp. Note on 1 Corinthians 2:14.)
But ye know him; for he dwelleth with you, and shall be in you. — The better text is,.... and is in you. The verbs are in the present tense, describing the receptivity of the disciples as opposed to the moral blindness of the world. They had, during our Lord’s work and teaching in their midst, exercised and strengthened their spiritual faculties. They had in part received the Spirit, and by that reception were prepared for the fuller gift. They knew Him. He was in their midst. He was then, and therefore should be in the future, a living power, dwelling in their inmost life.
