The Spirit Discloses Christ

it is not only because of Christ that we come to know the Spirit more fully, but actually in Christ. Indeed, it is apparently a principle of the divine Spirit's working that he declines to disclose himself in any other way (Jn. 16:13-15). He will not be known as he is in himself apart from Christ.
