The Spirit does not glorify Himself; He glorifies the Son… This is, to me, one of the most amazing and remarkable things about the biblical doctrine of the Holy Spirit. The Holy Spirit seems to hide Himself and to conceal Himself. He is always, as it were, putting the focus on the Son, and that is why I believe, and I believe profoundly, that the best test of all as to whether we have received the Spirit is to ask ourselves, what do we think of, and what do we know about, the Son. Is the Son real to us? That is the work of the Spirit. He is glorified indirectly; He is always pointing us to the Son.
