Charles H. Spurgeon on Psalms 11:3

"What CAN the righteous?" The can of the righteous is a limited can, confined to the rule of God's word; they can do nothing but what they can lawfully do. 2 Corinthians 13:8. "For we can do nothing against the truth, but for the truth:" Illud possumus, quod jure possumus. Wicked men can do anything; their conscience, which is so wide that it is none at all, will bear them out to act anything how unlawful soever, to stab, poison, massacre, by any means, at any time, in any place, whosoever standeth betwixt them and the effecting of their desires. Not so the righteous; they have a rule whereby to walk, which they will not, they must not, they dare not, cross. If therefore a righteous man were assured, that by the breach of one of God's commandments he might restore decayed religion, and re-settle it statu quo prius, his hands, head, and heart are tied up, he can do nothing, because their damnation is just who say (Romans 3:8), "Let us do evil that good may come thereof."
