If you are a Christian woman, there should be some degree of modesty, the same as if you are a Christian man. You would not want to cause another to stumble. What if you are a Christian woman, you're proud of your body, and wear a skimpy bikini to the beach. And a young Christian (young as in he just came to Christ) sees you and goes home and masterbates, thinking about you in that skimpy bikini. Have you caused him to sin? Perhaps you did not participate directly in his sin, i.e. you were not there actually having intercourse with him. But the picture in his mind is of you in that bikini. And as a result of his self sexual gratification he stumbles and loses his faith because he thought God had delivered him from his sin, now he feels shame, remorse, guilt, and he feels like a pervert. So he leaves the church. How can he go to the same church with you after what he has done?
