John 16:13

John 16:13. 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.

Is not that wonderful? As Jesus Christ said that he did not bear witness to himself, but spoke the words which his Father had given him, so the Spirit of God does not speak of himself, but he bears witness to the truth which Christ has revealed, and also makes known "things to come." But he will never reveal anything contrary to that which Christ has revealed in his Word. That which is to be revealed is that truth which was from the beginning. As we are taught it by the Divine Spirit, it becomes fresh truth to us, though it was ever in Christ’s eternal mind.
