LDS, mormons, what does this verse mean?? stones?

Cool, I want a seer stone. I'm not Christian but the more and more I look at my ex LDS faith it seems like an evil tool that pulls people away from Christianity. Christianity teaches that only through Christ it is possible to be saved... period. LDS teach that through your own works and suffering using your priesthood and your personal ability to receive revelation from God you may obtain something better than just being "saved". LDS don't like to praise Christ's death which in Christian teaching it is his death that was the greatest gift to the people. Through his death we were saved. But the LDS again don't like that the people of this earth were the only ones wicked enough to kill Christ. Maybe that is why they Mormons are seen as unChristian by some.
