" The Holy Spirit was poured out as the fruit of Resurrection and Ascension. And the Spirit is now the Power of God in us, working upwards towards Christ, to reproduce His life and Holiness in us, to fit us for fully receiving and showing forth Him in our lives.

We must take the lesson to heart; we can have as much of the Spirit as we are willing to have of His Holiness. Be full of the Spirit, must mean to us, Be fully holy. [. . .]

Be holy means, Be filled with the Spirit. If we inquire more closely how it is that this Holy Spirit makes holy, the answer is,—He reveals and imparts the Holiness of Christ. "
