Is Mormonism Christian?

See the video on Glen Beck's Testimony.  Just because they seem to be sincere and nice people, are they Christians?  Final authority is the Word of God.  Proverbs 14:12 says, There is a way that seems right to a man, but its end is the way to death. Beck thinks Mormonism is Christian, once he embraced Mormonism miracles happened in his life, seems like it was from God. But remember when Moses performed miracles in Egypt, Satan's servants, the magicians were able to do counterfeit miracles. (Exodus 7) Beck became popular and famous after he became a Mormon. Remember Satan told Jesus, in Matthew 4:8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory. 9 And he said to him, “All these I will give you, if you will fall down and worship me.”
