Beware of Mormons like Glenn Beck! They still believe in having many wives. Many people listen to him I know, but they are not considering that he is a liar even when he speaks the truth about politics. He is a Wolfe in sheep's clothing!
Praise the Lord for sending Jesus Christ! He set it straight about a man having many wives. He said this was not so "in the beginning", it was one man and one woman. This is how God designed marriage. If you are a Mormon reading this maybe you have never been told that Jesus corrected the whole culture's thinking about marriage.
