Jesus emphasized that the mind must be kept clean of immoral thoughts when he said: “Everyone that keeps on looking at a woman so as to have a passion for her has already committed adultery with her in his heart. ” ​ — Matt.
عیسی هم برای تأکید این موضوع چنین گفت :‏ « لیکن من به شما می‌گویم ،‏ هر کس به زنی نظر شهوت اندازد ،‏ همان دَم در دل خود با او زنا کرده است .‏ » —‏ مت ۵ :‏ ۲۸‏ .‏
