I have a fun hypothetical for Christians, particularly those who feel strongly that their religion requires "one man-one woman" marriages. Say a Muslim man in Saudi Arabia or some other Muslim country, who has two wives, converts to Christianity. Do you believe that God and Christianity would require him to put aside the second wife, or would they allow him to keep them both? Why or why not? Would the answer change if both wives had children with this man? Why or why not?
