Whether deeds deadened by sin, are revived by Penance?

Objections

Objection 1 : It would seem that deeds deadened by sin are not revived by Penance. Because just as past sins are remitted by subsequent Penance, so are deeds previously done in charity, deadened by subsequent sin. But sins remitted by Penance do not return, as stated above (Question [88], Articles [1],2). Therefore it seems that neither are dead deeds revived by charity.
Objection 2 : Further, deeds are said to be deadened by comparison with animals who die, as stated above (Article [4]). But a dead animal cannot be revived. Therefore neither can dead works be revived by Penance.
Objection 3 : Further, deeds done in charity are deserving of glory according to the quantity of grace or charity. But sometimes man arises through Penance to lesser grace or charity. Therefore he does not receive glory according to the merit of his previous works; so that it seems that deeds deadened by sin are not revived.
