Never forget that when we are dealing with any pleasure in its healthy and normal and satisfying form, we are, in a sense, on the Enemy’s (God’s) ground…He [God] made the pleasure: all our research so far has not enabled us to produce one. All we can do is to encourage the humans to take the pleasures which our Enemy [God] has produced, at at times, or in ways, or in degrees, which He [God] has forbidden.

C.S. Lewis
