We know that even saintly men have been given over in the flesh to Satan and to great afflictions for some very slight faults, since the divine mercy will not tolerate the very least spot or stain to be found in them on the day of judgment, and purges away in this world every spot of their filth, as the prophet, or rather God himself says, in order that he may commit them to eternity as gold or silver refined and needing no penal purification. “And,” he says,“I will clean purge away your dross, and I will take away all your sin; and after this you will be called the city of the just, a faithful city.” And again: “Just as silver and gold are tried in the furnace, so the Lord chooses hearts.” 18 And again: “The fire tries gold and silver, but man is tried in the furnace of humiliation.” And this also: “For the Lord chastens those whom he loves, and he disciplines every son whom he receives.” We see a clear instance of this in the case of the prophet and man of God in the third book of Kings who was immediately destroyed by a lion for a single disobedience, in which he was implicated not of set purpose nor by the fault of his own will but by the enticement of another. As the Scripture says of him: “It is the man of God, who disobeyed the word of the Lord, and the Lord delivered him to the lion, and it killed him according to the word of the Lord, which he spoke.” The punishment for his present offense and his careless error—together with the reward for his righteousness—for which the Lord gave over his prophet in this world to the destroyer appeared in the moderation and abstinence of the beast of prey, when that most savage creature did not dare even to taste the carcass that was given over to him.

Moreover, we know that even holy men have been given over bodily to Satan or to great sufferings on account of some slight sins. For the divine clemency does not permit the least blemish or stain to be found in them on the day of judgment. According to the words of the prophet, which are in fact God’s, he purges away all the dross of their uncleanness in the present so that he may bring them to eternity like fire-tried gold or silver, in need of no penal cleansing. “And I will,” he says, “utterly purge away your dross, and I will remove all your alloy. And after this you shall be called the city of the righteous, the faithful city.” And again: “Just as silver and gold are tried in a furnace, so the Lord chooses hearts.” And again: “Fire tries gold and silver, but a man is tried in the furnace of humiliation.” And this also: “The Lord chastises the one whom he loves, and he scourges every son whom he receives.” In the Third Book of Kings we see this clearly exemplified in the case of that prophet and man of God who was immediately destroyed by a lion because of a single sin of disobedience that he contracted not even out of the workings or the viciousness of his own will but through another’s deceptive behavior. Scripture says of him, “That is the man of God who was disobedient to the word of the Lord, and the Lord delivered him over to a lion, and it destroyed him, according to the word of the Lord which he spoke.” When this happened, the very sparingness and abstinence of the predator (for the voracious beast did not dare to eat anything at all of the corpse that had fallen to him) appeared as not only the punishment for his present offense and heedless error but also as the deserts of his righteousness, on account of which the Lord delivered over his prophet for a time to the tormenter. - "Conference 7.25.2-26.1"

No one doubts that when the judgment of the heart goes astray and is seized by the night of ignorance, our thoughts and our deeds, which proceed from the deliberation of discretion, are involved in the greater darkness of sin. Finally, because he never had this eye of discretion, he who by God’s judgment first deserved to rule over the people of Israel was cast out of his kingdom like something dark out of a healthy body. Having been deceived by the darkness and error of this light, he decided that his own sacrifices were more acceptable to God than obedience to Samuel’s command, and in the very act by which he had hoped that he would propitiate the divine majesty he committed sin instead. Ignorance of this discretion, I say, constrained Ahab, the king of Israel, after the triumph of the glorious victory that had been conceded to him by God’s favor, to believe that his own mercy was better than the very severe execution of the divine command, which seemed to him to be a cruel decree. Enfeebled by this thought, he wished to temper a bloody victory with clemency and, having been made dark throughout his body because of his impudent mercy, he was condemned to a death from which there was no recourse. - "Conference 2.2.6-3.2"

For no one can doubt that when the judgment of our heart goes wrong and is overwhelmed by the night of ignorance, our thoughts and deeds, which are the result of deliberation and discretion, must be involved in the darkness of still greater sins. Finally, the man who in the judgment of God was the first to be worthy to be king of his people Israel, because he was lacking in this “eye” of discretion, was, as if his whole body were full of darkness, actually cast down from the kingdom. While being deceived by the darkness of this “light” and in error, he imagined that his own offerings were more acceptable to God than obedience to the command of Samuel. And so he failed in that very act by which he had hoped to propitiate the Divine Majesty. And ignorance, I say, of this discretion led Ahab the king of Israel, after a triumph and splendid victory which had been granted to him by the favor of God, to imagine that mercy on his part was better than the stern execution of the divine command, which seemed a cruel rule to him. Moved by this consideration, while he desired to temper a bloody victory with mercy, he was on account of his indiscriminating clemency rendered full of darkness in his whole body and condemned irreversibly to death.
