The Treatises of Cyprian
Book 12c › Chapter 45
That hope is of future things, and therefore that our faith concerning those things which are promised ought to be patient
In the Epistle of Paul to the Romans: “We are saved by hope. But hope that is seen is not hope; for what a man sees, why does he hope for? But if we hope for what we see not, we hope for it in patience.”
