As we promised in the immediately preceeding book, this, the last of the whole work, shall contain a discussion of the eternal blessedness of the city of God. This blessedness is named eternal, not because it shall endure for many ages, though at last it shall come to an end, but because, according to the words of the gospel, “of His kingdom there shall be no end.” Neither shall it enjoy the mere appearance of perpetuity which is maintained by the rise of fresh generations to occupy the place of those that have died out, as in an evergreen the same freshness seems to continue permanently, and the same appearance of dense foliage is preserved by the growth of fresh leaves in the room of those that have withered and fallen; but in that city all the citizens shall be immortal, men now for the first time enjoying what the holy angels have never lost. And this shall be accomplished by God, the most almighty Founder of the city. For He has promised it, and cannot lie, and has already performed many of His promises, and has done many unpromised kindnesses to those whom He now asks to believe that He will do this also.
For it is He who in the beginning created the world full of all visible and intelligible beings, among which He created nothing better than those spirits whom He endowed with intelligence, and made capable of contemplating and enjoying Him, and united in our society, which we call the holy and heavenly city, and in which the material of their sustenance and blessedness is God
