I've been dealing with someone of the Mormon belief. This person is for polygamy and says that the rapture is unbiblical (basing is on Rev. 21:1-2). I know both of these views are wrong, but I am having a hard time in stating my position clearly to the person. I know that marriage is one man and one woman. I also know that believer will be spared from the tribulation, not merely getting through it. Any suggestions? Thanks.
