Can a person merit any supernatural reward for good deeds performed while he is in mortal sin?
A. A person cannot merit any supernatural reward for good deeds performed while he is in mortal sin; nevertheless, God rewards such good deeds by giving the grace of repentance; and, therefore, all persons, even those in mortal sin, should ever strive to do good. Q. Does God reward anything but our good works? A. God rewards our good intention and desire to serve Him, even when our works are not successful. We should make this good intention often during the day, and especially in the morning.
