Ambrose of Milan, on Ps 94:10

“Forty years long was I offended with that generation, and I said: These always err in heart.”

“"See, O people, the grace of Christ about you. Even while you are harassed on earth, you have possessions in heaven. There, then, let your heart be, where your possession is." This is the rest that is due the just and is denied the unworthy. Wherefore says the Lord, "As I swore in my wrath, that they shall not enter into my rest." For they who have not known the ways of the Lord shall not enter into the rest of the Lord, but to the individual who has fought the good fight and has finished his course it is said, "Turn to your rest." It is a blessed rest to pass by the things of the world and to find repose in the celestial fellowship of the mysteries that are above the world. This is the rest toward which the prophet hastened, saying, "Who will give me wings like a dove and I will fly and be at rest?" The holy person knows that his rest is in heaven, and to this rest he says his soul must turn. Therefore his soul was in its rest, to which he says it must return. This is the rest of the great sabbath, in which each of the saints is above the sensible things of the world, devoting himself entirely to deep and invisible mystery and cleaving to God. This is that rest of the sabbath on which God rested from all the works of his world.”
