Young men, “Flee from sexual immorality” (1 Corinthians 6:18) if you love life. “Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient” (Ephesians 5:6). Flee from the opportunity of it–from the company of those who might draw you into it–from the places where you might be tempted to do it. . . . Flee from talking about it. It is one of the things that ought not even be hinted about in conversation. You cannot even touch black grease without getting your hands dirty. Flee from the thoughts of it; resist them, destroy them, pray against them–make any sacrifice rather than give way to them. Imagination is the hotbed where this sin is too often hatched. Guard your thoughts, and there will be little fear about your actions.
