Gaius Marius Victorinus : What are these "riches of the glory of God?" They are "being strengthened with might through his Spirit," so that they may be strong against the sinful nature, the desires of the flesh and the dreadful powers of this world. This strengthening happens through the Spirit of God. But how are persons strengthened and made firm through the Spirit of God? By "Christ's dwelling in the inner man," he says. For when Christ begins to dwell in the inner citadel of the soul, persons are made strong by might through the Spirit. In this way everything of a hostile nature is evicted. — EPISTLE TO THE Ephesians 1.3.16-17 John Chrysostom : "That He would grant you according to the riches of His glory that ye may be strengthened with power through His Spirit in the inward man; that Christ may dwell in your hearts through faith." Mark with what insatiable earnestness he invokes these blessings upon them, that they may not be tossed about. But how shall this be effected? By the "Holy Spirit in your inward man, that Christ may dwell in your hearts through faith." How again shall this be? However, he does not ask the whole of God, but demands of them also faith and love, and not simply love, but love "rooted and grounded," so that neither any blasts can shake it, nor any thing else overturn it. He had said, that "tribulations" are "glory," and if mine are so to you, he would say, much more will your own be: so that to be afflicted is no token of men being forsaken, for He who hath wrought so great things for us, never would do this. But how doth Christ dwell in the hearts? Hear what Christ Himself saith, "I and my Father will come unto him, and make our abode with him." He dwelleth in those hearts that are faithful, in those that are "rooted" in His love, those that remain firm and unshaken. "That ye may be" thoroughly "strong," saith he; so that there is great strength needed. — Homily on Ephesians 7
