For Or but (the objector may reply) if the truth of God hath more abounded Has been more abundantly shown; through my lie If my lie, that is, practice contrary to truth, conduces to the glory of God, by making his truth shine with superior advantage; why am I yet judged as a sinner And arraigned for that which is attended with such happy consequences? Can my conduct be said to be sinful at all? Ought I not to do what would otherwise be evil, that so much good may come? To this the apostle does not deign to give a direct answer, adding, whose damnation, or condemnation, is just. The condemnation of all, who either speak or act in this manner. Here the apostle teaches expressly the unlawfulness of doing evil, any evil, on the pretence of promoting what is good. Such a pretence, if allowed, would justify the greatest crimes. This, however, the apostle here signifies they were slanderously reported as teaching; probably on a misinterpretation of their doctrine, that the greatness of the sins of which the Gentiles were guilty, rendered God's goodness in sending Christ to die for them the more illustrious.
