It is seldom that any of our [bad habits or flaws] are made to disappear by a mere process of natural extinction. At least, it is very seldom that this is done through the instrumentality of reasoning…[or by] the mere force of mental determination. But what cannot be thus destroyed may be dispossessed–and one taste may be made to give way to another, and to lose its power entirely as the reigning affection of the mind…. [T]he heart[‘s]…desire for having some one object or other, this is unconquerable…. [T]he only way to dispossess [the heart] of an old affection is by the expulsive power of a new one…. It is…when admitted into the number of God’s children, through the faith that is in Jesus Christ, [that] the spirit of adoption is poured upon us–it is then that the heart, brought under the mastery of one great and predominant affection, is delivered from the tyranny of its former desires, and is the only way in which deliverance is possible.
-Thomas Chalmers, “The Expulsive Power of a New Affection”
