That thing is sin

If you wish to determine the lawfulness of a pleasure, follow this rule:

"Whatever weakens your reason, impairs the tenderness of your conscience, obscures your sense of God,, or takes away the relish of spiritual things; whatever increases the authority of your body over your mind, that thing is sin." -- Mother of John Wesley

"Whether therefore you eat, or drink, or whatsoever you do, do all to the glory of God" 1 Cor. 10:31

Test for our love of God

"You shall not be known by special rites or habits, not by a special form of dress or manner of speech; not by special austerities and unusual customs, like the Pharisees, the Essenes or the scribes, but by deep, genuine, and tender affection. And it is well known it was this which eminently distinguished the first Christians, and was the subject of remark by the surrounding pagans. 'See,' said the pagan, 'see how they love one another! They are ready to lay down their lives for each other.' " (from Barnes' Notes, Electronic Database Copyright © 1997, 2003, 2005 by Biblesoft)
