3. For in as many days as this world was made, in so many thousand years shall it be concluded. And for this reason the Scripture says: “Thus the heaven and the earth were finished, and all their adornment. And God brought to a conclusion upon the sixth day the works that He had made; and God rested upon the seventh day from all His works.” This is an account of the things formerly created, as also it is a prophecy of what is to come. For the day of the Lord is as a thousand years; and in six days created things were completed: it is evident, therefore, that they will come to an end at the sixth thousand year. 4. And therefore throughout all time, man, having been moulded at the beginning by the hands of God, that is, of the Son and of the Spirit, is made after the image and likeness of God: the chaff, indeed, which is the apostasy, being cast away; but the wheat, that is, those who bring forth fruit to God in faith, being gathered into the barn. And for this cause tribulation is necessary for those who are saved, that having been after a manner broken up, and rendered fine, and sprinkled over by the patience of the Word of God, and set on fire [for purification], they may be fitted for the royal banquet. As a certain man of ours said, when he was condemned to the wild beasts because of his testimony with respect to God: “I am the wheat of Christ, and am ground by the teeth of the wild beasts, that I may be found the pure bread of God.”
