15 “He has not dealt with us according to our sins”. Thanks unto God, because He has vouchsafed this. We have not received what we were deserving of: “He has not dealt with us according to our sins, nor rewarded us according to our wickednesses.” “For as the height of heaven above the earth, so has the Lord confirmed His mercy toward them that fear Him”. Observe the heaven: everywhere on every side it covers the earth, nor is there any part of the earth not covered by the heaven. Men sin beneath heaven: they do all evil deeds beneath the heaven; yet they are covered by the heaven. Thence is light for the eyes, thence air, thence breath, thence rain upon the earth for the sake of its fruits, thence all mercy from heaven. Take away the aid of heaven from the earth: it will fail at once. As then the protection of heaven abides upon the earth, so does the Lord's protection abide upon them that fear Him. You fear God; His protection is above you. But perhaps you are scourged, and conceive that God has forsaken you. God has forsaken you, if the protection of heaven has forsaken the earth.
16. “Look, how wide the east is from the west; so far has He set our sins from us”. They who know the Sacraments know this; nevertheless, I only say what all may hear. When sin is remitted, your sins fall, your grace rises; your sins are as it were on the decline, your grace which frees you on the rise. “Truth springs from the earth.” What means this? Your grace is born, your sins fall, you are in a certain manner made new. You should look to the rising, and turn away from the setting. Turn away from your sins, turn unto the grace of God; when your sins fall, thou rises and profitest....One region of the heaven falls, another rises: but the region which is now rising will set after twelve hours. Not like this is the grace which rises unto us: both our sins fall for ever, and grace abides for ever.
17. “Yea, like as a father pities his own children, even so has the Lord had mercy on them that fear Him”. Let Him be as angry as He shall will, He is our Father. But He has scourged us, and afflicted us, and bruised us: He is our Father. Son, if you bewail, wail beneath your Father; do not so with indignation, do not so with the puffing up of pride. What you suffer, whence you mourn, it is medicine, not punishment; it is your chastening, not your condemnation. Do not refuse the scourge, if you dost not wish to be refused your heritage: do not think of what punishment you suffer in the scourge, but what place you have in the Testament.
18. “For He knows our forming”: that is, our infirmity. He knows what He has created, how it has fallen, how it may be repaired, how it may be adopted, how it may be enriched. Behold, we are made of clay: “The first man is of the earth, earthy: the second man is the Lord from heaven.” He sent even His own Son, Him who was made the second man, Him who was God before all things. For He was second in His coming, first in His returning: He died after many, He arose before all. “He knows our forming.” What forming? Ourselves. Why do you say that He knows? Because He has pitied. “Remember that we are but dust.” Addressing God Himself, he says, “Remember,” as if God could forget: He perceives, He knows in such a manner that He cannot forget. But what means, “Remember”? Let your mercy continue towards us. You know our forming; forget not our forming, lest we forget your grace.
19. “Man, his days are but as grass”. Let man consider what he is; let not man be proud. “His days are but as grass.” Why is the grass proud, that is now flourishing, and in a very short space dried up? Why is the grass proud that flourishes only for a brief season, until the sun be hot? It is then good for us that His mercy be upon us, and from grass make gold. “For he flourishes as a flower of the field.” The whole splendour of the human race; honour, powers, riches, pride, threats, is the flower of the grass. That house flourishes, and that family is great, that family flourishes; and how many flourish, and how many years do they live! Many years to you, are but a short season unto God. God does not count, as you do. Compared with the length and long life of ages, all the flower of any house is as the flower of the field. All the beauty of the year hardly lasts for the year. Whatever there flourishes, whatever there is warmed with heat, whatever there is beautiful, lasts not; nay, it cannot exist for one whole year. In how brief a season do flowers pass away, and these are the beauty of the herbs! This which is so very beautiful, this quickly falls. Inasmuch then as He knows as a father our forming, that we are but grass, and can only flourish for a time; He sent unto us His Word, and His Word, which abides for evermore, He has made a brother unto the grass which abides not. Wonder not that you shall be a sharer of His Eternity; He became Himself first a sharer of your grass. Will He who assumed from you what was lowly, deny unto you what is exalted in respect of you?
20. “The wind shall go over on it, it shall not be; and the place thereof shall know it no more”. For he is not speaking of grass, but of that for whose sake even the Word became grass. For you are man, and on your account the Word became man. “All flesh is grass:” “and the Word was made flesh.” How great then is the hope of the grass, since the Word has been made flesh? That which abides for evermore, has not disdained to assume grass, that the grass might not despair of itself.
