Watching nudity isn't okay, says Holmes, explaining that Jesus said those who look at others with lustful intent have already committed adultery. "Seeing naked women on the screen — or naked men — causes a man, or woman, to sin with their minds and their desires, and often with their bodies." Based on Matthew 5:28–29, he adds, "If your right eye causes you to sin, tear it out and throw it away."

2. Am I Longing to See God?
