Susanna Wesley

“Whatever weakens your reason, impairs the tenderness of your conscience, obscures your sense of God, takes off your relish for spiritual things, whatever increases the authority of the body over the mind, that thing is sin to you, however innocent it may seem in itself.”

“How would you judge the lawfulness or unlawfulness of "pleasure?" Use this rule:Whatever weakens your reason, impairs the tenderness of your conscience, obscures your sight of God, takes from you your thirst for spiritual things or increases the authority of your body over your mind, then that thing to you is evil.By this test you may detect evil no matter how subtly or how plausibly temptation may be presented to you.”
