Character-development and heaven

Numerous philosophers in recent decades have argued that a partial explanation for how the blessed in heaven are impeccable while remaining free and responsible is that they have cultivated or developed such a virtuous character prior to heaven (when they were able to sin) that once in heaven they are incapable of acting contrary to their virtuously cultivated characters. Further, because the agents are at least partially responsible for the construction of their characters, they can be considered free and responsible with regard to the choices or actions such virtuous characters allow. In what follows I will argue that the impeccability of the blessed is not achieved through a character-development process performed by the blessed themselves.
