multiple wives - want to have multiple wives?
Christians cannot marry two or more wives but why can muslims and other religions like mormons can marry as many as they want as long as they can provide him their needs? What's their belief of having two or more wives? I'm not against muslims but I just want to know why they need to have multiple wives?
