"It is seldom that any of our bad habits or flaws disappear by reasoning, or by the force of mental determination. The heart's desire for some particular ultimate object may be conquered, but it's desire to have SOME object is unconquerable... The only way to dispossess the heart of an old affection is through the expulsive power of a new one."
-- Thomas Chalmers, in his sermon "The Expulsive Powers of a New Affection"
