Requitals correspond to our deserts, even if many people think they do not. To some, divine justice gives eternal life; to others, eternal chastisement. Each will be requited according to his actions–according to whether he has passed through this present life in a virtuous or in a sinful manner. The degree or quality of the requital will accord with the state induced in each by either the passions or the virtues, and the differing effects these have had.
~St Gregory of Sinai
