“There are two ways in which a practical moralist may attempt to displace from the human heart its love of the world—either by a demonstration of the world's vanity, so as 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 as 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.”

—Thomas Chalmers, “The Expulsive Power of a New Affection”

“If I may speak from my own experience, I find that to keep my eye simply on Christ, as my peace and my life, is by far the hardest part of my calling.... It seems easier to deny self in a thousand instances of outward conduct, than in its ceaseless endeavors to act as a principle of righteousness and power.”

—John Newton, Works
