“It [that is, the neglect of the duty of mortification] hardens them by begetting in them a persuasion that they are in as good condition as the best professors. Whatever they see in them is so stained, for want of this mortification, that it is of no value with them. They have zeal for religion; but it is accompanied with want of forbearance and universal righteousness. They deny prodigality, but with worldliness: they separate from the world, but live wholly to themselves, taking no care to exercise lovingkindness in the earth. Or they talk spiritually, and live vainly; mention communion with God, and are every way conformed to the world; boasting of forgiveness of sin, and never forgiving others; and with such consierations do poor creatures harden their hearts in their uregeneracy.”
