“There are two ways in which a practical moralist may attempt to displace from the human heart its love for the world — either by a demonstration of the world’s vanity, so that the heart shall be prevailed upon simply to withdraw its regards from an object that is not worthy of it; or, by setting forth another object, even God, as more worthy of its attachment, so that the heart shall be prevailed upon not to resign an old affection, which shall have nothing to succeed it, but to exchange an old affection for a new one... From the constitution of our nature, the former method is altogether incompetent and ineffectual, and the latter method will alone suffice for the rescue and recovery of the heart from the wrong affection that domineers over it.”
