Is it so bad if I just think about sex with someone? I didn’t really do it. - Sexuality - TouchPoints

Exodus 20:17“You must not covet your neighbor’s house. You must not covet your neighbor’s wife.”

Matthew 5:27-28“You have heard the commandment that says, ‘You must not commit adultery.’ But I say, anyone who even looks at a woman with lust has already committed adultery with her in his heart.”

Lust is adultery in the heart. It is true that when you imagine having sex with someone you have not consummated the act with that person physically. But in your heart, you have.
