Many men who live in ways which are not agreeable to the rules of God’s Word, yet are not sensible of it. And it is a difficult thing to make them so because the same lust that leads them into that evil way, blinds them in it. — Thus, if a man [lives] a way of malice or envy, the more malice or envy prevails, the more will it blind his understanding to approve of it. The more a man hates his neighbor, the more will he be disposed to think that he has just cause to hate him, and that his neighbor is hateful, and deserves to be hated, and that it is not his duty to love him. So if a man live in any way of lasciviousness, the more his impure lust prevails, the more sweet and pleasant will it make the sin appear, and so the more will he be disposed and prejudiced to think there is no evil in it.
