Matthew 5:27. ‘”You have heard that it was said, ‘You shall not commit adultery.’ 28. But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. 29. If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. 30. And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.”‘
Christians know that porn is wrong. It robs the spouse of the sanctity of the marriage, honor, love, reapect, fulfillment with the spouse, feelings of inadequacy leap in as does doubt, distrust, shame, lies. It is no good in a marriage, had no place there or outside a marriage either. It is sin. Just because it is a sin you want to do does not mean it is boot sin. It is just sin you want to do. It robs your spouse. It dishonor them. It does. You can think it doesn’t all day but it does. It leaves you selfishly getting what you want and your spouse lonely and sad and without security in the marriage. No one speaks of it because so common as a secret sin. There is no secret sin, though. God sees. He is in the room with you. He detests it, I assure you. No judgment, just truth of it. Some battles are worth fighting and your marriage is sacred ground which should be protected, where everyone feels safe and loved and honored.
