"Too often readers turn to books so they can vicariously experience sin...books that pander to their sexual fantasies, to their dreams of wealth and power, to their dark, secret obsessions with sadistic violence or occult nightmares. Reading the pornographic descriptions and acts of brutality gratifies their secret desires, giving them perverted pleasures in the privacy of their own imaginations."
Matthew 5:27-28 "You have heard that it was said to those of old, 'YOU SHALL NOT COMMIT ADULTERY.' 28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
"The application is inescapable. Just as we must avoid sinful actions, we must avoid sinful imaginings. If our eyes lead us into sin, it is better to gouge them out that allow them to lead us to Hell."
