The Holy Spirit is the coming of the man Jesus, who is the Son of God, to other men who are not this but with whom He still associates* And the witness of the Holy Spirit is the disclosure to these men, and therefore their discovery, of the fact that because they are associated with Him they can be called what they are certainly not called of themselves, and be what they can certainly never become or be of themselves children of God, children of light who in the midst of death are freed from the fear of death because as sinners they are freed from the curse of sin, and as such messengers to all those who, because they do not see the light, are still in darkness, but are not to remain in this darkness.

We know that God is He whom we do not know, and that our ignorance is precisely the problem and the source of our knowledge. The Epistle to the Romans is a revelation of the unknown God; God chooses to come to man, not man to God. Even after the revelation man cannot know God, for he is ever the unknown God. In manifesting himself to man he is farther away than before.

While it is beyond our comprehension that eternity should meet us in time, yet it is true because in Jesus Christ eternity has become time.
