99. See what the voice of the Lord uttered concerning the Holy Spirit. The Son of God came, and because He had not yet shed forth the Spirit, He declared that we were living like little children without the Spirit. He said that the Spirit was to come Who should make of these little children stronger men, by an increase, namely, of spiritual age. And this He laid down not that He might set the power of the Spirit in the first place, but that He might show that the fulness of strength consists in the knowledge of the Trinity.
