Cyril of Alexandria: "The Holy Spirit dwells in the saints"

This is from the blog Dover Beach:

“The Holy Spirit dwells in the saints and remains with them for ever, if they cleanse the eye of their understanding by cleaving to every sound doctrine and by resolutely pursuing every virtue, and thus maintain the grace within themselves. For Christ says that those who are in the world, that is, those who are preoccupied with the things of this world and choose to love earthly things, are unable to contain or to behold the Spirit.”

--Saint Cyril of Alexandria
