Charles Spurgeon Commentary John 16:13-14

"Howbeit when he, the Spirit of truth, is come, he shall guide you into all the truth: for he shall not speak from himself; but what things soever he shall hear, [these] shall he speak: and he shall declare unto you the things that are to come. He shall glorify me: for he shall take of mine, and shall declare [it] unto you." — John 16:13-14 (ASV)

However, when he, the Spirit of truth, has come, he will guide you into all truth; for he will not speak of himself, but whatever he hears, that he will speak; and he will show you things to come. He will glorify me:

Now that is a sure mark of the Holy Spirit. If there is any spirit which does not glorify Christ, it is not the Holy Spirit; it is not the Comforter.

If you hear any doctrine which detracts from the dignity of Christ's nature, from the glory of Christ's person, from the perfection and the necessity of Christ's sacrifice, you may depend on it that it is not the doctrine of God. Reject it at once. It may poison you. It cannot build you up. He will glorify me.

Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself, but whatsoever he shall hear, that shall he speak: and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you.

That spirit, which does not glorify Christ, is not the spirit of God. By this you will discern between the spirit of error and the Spirit of truth.

For he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will show you things to come. He shall glorify me:

That is the distinctive mark of the Spirit of God. If anyone says that he speaks by the Spirit, you can test him in this way: Does what he says glorify Christ? If not, away with him, for he is not speaking as the Holy Spirit speaks.
