Can a person who repents of mortal sin regain their good works?


In another topic discussion we got into a secondary discussion about if a person who commits a mortal sin and loses all their supernatural merits can regain those same merits by repenting?

For example if one has been a good Christian and received the sacraments, performed acts of charity for most of their life and then was lead astray and consciously rejected Church Teaching and became an open adulterer for example could this person repent, and then be regain all the prior supernatural merits they previously had gained from God? Or must such a person start over all again with nothing but his own repentance and devotion to God? This gets into a concept of not just salvation but higher reward in heaven for those who are saved but fully respond to God’s grace with extraordinary works.

Would appreciate your comments.
