10 Thus have the counsels of avarice been refuted; but now let the Lord say the same words, now let righteousness speak: the words will be the same, but not the same the meaning. “Keep for yourself,” says the Lord, “consult for the future.” Now ask Him, “Where shall I keep?” “You shall have treasure in heaven, where no thief approaches, nor moth corrupts.” Against what an enduring future shall you keep it! “Come, you blessed of My Father, receive the kingdom prepared for you from the foundation of the world.” And of how many days this kingdom is, the end of the passage shows.
For after He had said of those on the left hand, “So these shall go away into everlasting burning;” of those on the right hand He says, “but the righteous into life eternal.” This is “consulting for the future.” A future which has no future beyond it. Those days without an end are called both “days,” and “a day.” For one when he was speaking of those days, says, “That I may dwell in the house of the Lord for length of days.” And they are called a day, “This day have I begotten you.” Now those days are one day; because there is no time, in it; that day is neither preceded by a yesterday, nor succeeded by a tomorrow. So then let us “consult for the future:” the words indeed which avarice said to you are not different in terms from this, yet by them is avarice overthrown.
