thus gives us to understand that God did not respect his offering because it was not rightly "distinguished" in this, that he gave to God something of his own but kept himself to himself. For this all do who follow not God's will but their own, who live not with an upright but a crooked heart, and yet offer to God such gifts as they suppose will procure from Him that He aid them not by healing but by gratifying their evil passions. And this is the characteristic of the earthly city, that it worships God or gods who may aid it in reigning victoriously and peacefully on earth not through love of doing good, but through lust of rule. The good use the world that they may enjoy God: the wicked, on the contrary, that they may enjoy the world would fain use God,--those of them, at least, who have attained to the belief that He is and takes an interest in human affairs. For they who have not yet attained even to this belief are still at a much lower level. Cain, then, when he saw that God had respect to his brother's sacrifice, but not to his own, should have humbly chosen his good brother as his example, and not proudly counted him his rival. But he was wroth, and his countenance fell. This angry regret for another person's goodness, even his brother's, was charged upon him by God as a great sin. And He accused him of it in the interrogation, "Why art thou wroth, and why is thy countenance fallen?" For God saw that he envied his brother, and of this He accused him. For to men, from whom the heart of their fellow is hid, it might be doubtful and quite uncertain whether that sadness bewailed his own wickedness by which, as he had learned, he had displeased God, or his brother's goodness, which had pleased God, and won His favourable regard to his sacrifice. But God, in giving the reason why He refused to accept Cain's offering and why Cain should rather have been displeased at himself than at his brother, shows him that though he was unjust in "not rightly distinguishing," that is, not rightly living and being unworthy to have his offering received, he was more unjust by far in hating his just brother without a cause.
