Whether the effect of subsequent Penance is to quicken even dead works?

Objections

Objection 1 : It would seem that the effect of subsequent Penance is to quicken even dead works, those, namely, that were not done in charity. For it seems more difficult to bring to life that which has been deadened, since this is never done naturally, than to quicken that which never had life, since certain living things are engendered naturally from things without life. Now deadened works are revived by Penance, as stated above (Article [5]). Much more, therefore, are dead works revived.
Objection 2 : Further, if the cause be removed, the effect is removed. But the cause of the lack of life in works generically good done without charity, was the lack of charity and grace. which lack is removed by Penance. Therefore dead works are quickened by charity.
Objection 3 : Further, Jerome in commenting on Agg. i, 6: "You have sowed much," says: "If at any time you find a sinner, among his many evil deeds, doing that which is right, God is not so unjust as to forget the few good deeds on account of his many evil deeds." Now this seems to be the case chiefly when past evil "deeds" are removed by Penance. Therefore it seems that through Penance, God rewards the former deeds done in the state of sin, which implies that they are quickened.
