Nicene and Post-Nicene Fathers: Series I/Volume II/City of God/Book XIX/Chapter 20
Chapter 20.—That the Saints are in This Life Blessed in Hope.
Since, then, the supreme good of the city of God is perfect and eternal peace, not such as mortals pass into and out of by birth and death, but the peace of freedom from all evil, in which the immortals ever abide; who can deny that that future life is most blessed, or that, in comparison with it, this life which now we live is most wretched, be it filled with all blessings of body and soul and external things? And yet, if any man uses this life with a reference to that other which he ardently loves and confidently hopes for, he may well be called even now blessed, though not in reality so much as in hope. But the actual possession of the happiness of this life, without the hope of what is beyond, is but a false happiness and profound misery. For the true blessings of the soul are not now enjoyed; for that is no true wisdom which does not direct all its prudent observations, manly actions, virtuous self-restraint, and just arrangements, to that end in which God shall be all and all in a secure eternity and perfect peace.
