Gregory the Great, on Eccl 9:10

“Whatsoever thy hand is able to do, do it earnestly: for neither work, nor reason, nor wisdom, nor knowledge shall be in hell, whither thou art hastening.”

“Since therefore the hours flee with their moments, act, dearest brothers, so that they may be retained in the reward of good work. Hear what the wise Solomon says: "Whatever your hand is able to do, work at it earnestly, for there will be neither work, nor knowledge, nor reason, nor wisdom in the underworld, to which you are hastening." Since therefore we do not know the time of coming death, and after death we cannot work, it remains that before death we seize the time that has been granted. For thus, yes thus, death itself when it comes will be conquered, if before it comes it is always feared.”
