Never forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on [our Heavenly Father's] ground... It is His invention... He made the pleasures... All [Satan and his devils] can do is to encourage... humans to take the pleasures which our [God] has produced, at times, or in ways, or in degrees, which He has forbidden. Hence [they] always try to work away from the natural condition of any pleasure to that in which it is least natural, least redolent of its Maker, and least pleasurable. An ever increasing craving for and ever diminishing pleasure is the formula... To get a man's soul and give him nothing in return - that is what really gladdens [the heart of Satan and his devils].
