Didymus the Blind, 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.”

“May your action be according to your ability! "Do with your might!" Act, according to the might you have received.… That might consists in the gifts of grace from the Holy Spirit. The one who has might and still does not increase his spiritual capacity does not use his might. The one, however, who forcefully does more than is right, not out of real desire, but out of ambition or for another reason, commits a sin.…The beginner acts like a novice, the one who has made progress like one who is on his way, the one who has reached perfection like one who is perfect. Thus, one has to act in accordance with one's ability. If you are not weak, do not act in a way that would diminish your ability to assert your will. On the other hand, do not attempt something which you cannot do!”
