It serves no purpose for my former-Mormon friends and me to continue to reach out and witness to people in Mormon churches, if they then accept the deception and leave, become disaffected with all religion and choose never to go to any church again or even become more callous toward God than we are in our fallen nature. I am thankful that when my time came, the rug was not ripped from under my feet and that I fell forever. I don’t want that for anyone else, especially the people I’ve known and cared about most of my life. I want people to become saved, evaluate what they believe, find a good Christian church, glorify God and enjoy Him forever. John Calvin articulated it well (Institutes of the Christian Religion, Book I, Chapter 6): “Error never can be eradicated from the heart of man until the true knowledge of God has been implanted in it.”
How is the eradication of error to be accomplished? Not by focusing on the error, but by magnifying the truth. The popularity of false prophets is nothing new, so combating them is an old struggle for God’s true prophets. For example, when God’s oracle to Israel, Jeremiah, was vexed by the influence of false teachers, the LORD’s instruction to the prophet was to focus on proclaiming truth. (Jeremiah 23:23, 28-29) “Am I a God at hand, declares the LORD, and not a God far away? … Let the prophet who has a dream tell the dream, but let him who has my word speak my word faithfully. What has straw in common with wheat? declares the LORD. Is not my word like fire, declares the LORD, and like a hammer that breaks the rock in pieces?”
Likewise, Christians are to elevate the truth and allow the false to diminish as a result.
Joseph Smith’s polygamy is not a good enough reason to leave Mormonism. The proven pseudepigraphy of the Book of Abraham and its implications for Smith’s credibility in his testimony of the Book of Mormon, is not a good enough reason to leave Mormonism. Not even the irrefutable evidence of Smith’s involvement in occult practices is a good enough reason to leave Mormonism. These are earnest considerations, but the only reason to abandon the false christ of Mormonism or any other cult system is to gain a person: Jesus Christ. Sometimes the cost of gaining Him is little and sometimes the cost is high, but it never comes close to the price He paid for His people. He is the only way, the truth and the life.
