12:1 Now - For now thou art most able to do it; and it will be most acceptable to God, and most comfortable to thyself, as the best evidence of thy sincerity, and the best provision for old age and death. Evil days - The time of old age, which is evil; burdensome in itself, and far more grievous when it is loaded with the sad remembrance of youthful follies, and with the dreadful prospect of approaching death and judgment. No pleasure - My life Is now bitter and burdensome to me: which is frequently the condition of old age.
12:1-7 We should remember our sins against our Creator, repent, and seek forgiveness. We should remember our duties, and set about them, looking to him for grace and strength. This should be done early, while the body is strong, and the spirits active. When a man has the pain of reviewing a misspent life, his not having given up sin and worldly vanities till he is forced to say, I have no pleasure in them, renders his sincerity very questionable. Then follows a figurative description of old age and its infirmities, which has some difficulties; but the meaning is plain, to show how uncomfortable, generally, the days of old age are. As the four verses, 2-5, are a figurative description of the infirmities that usually accompany old age, ver. 6 notices the circumstances which take place in the hour of death. If sin had not entered into the world, these infirmities would not have been known. Surely then the aged should reflect on the evil of sin.
