Seriously. It is hard to imagine being less popular. We’ve often joked that we are on Mormon and Jehovah’s Witness “do not call” lists, because I’m glad to take the time to visit with them when they come to my door.
But this was different. Some Mormon neighbors were having a Christmas party and put in a plug for the missionaries they were hosting. I introduced myself, told them where we lived and said, “We should talk.” They were excited at the time, but never came by. Hmmmmmm . . .
These folks are notoriously hard to convert, but if they are going to come to you then you might as well be equipped to offer some brief challenges to them. You never know how God might use your efforts to save someone – especially when one of their pair is usually a junior member who hasn’t been in the cult as long. Worst-case scenario: You keep them from telling their falsehoods to one of your neighbors.
More importantly, you and your loved ones should know the basics of why these are cults. It is easier to play defense (keeping people out of false religions) than offense (converting them away from false religions). Far too many people, including some of their members, think they are just different Christian denominations.
My standard approach with Jehovah’s Witnesses is to focus like a friendly pit pull on a couple things: First, their Bible’s mistranslation of John 1:1 (“a God” instead of “God,” as all the ancient manuscripts say). They will try to change the subject but I keep bringing them back in the most polite ways. With so much evidence regarding what the originals said, why would their Bible get it wrong?
Then I offer them literature, knowing they aren’t allowed to take it. I emphasize how my religion — Christianity — tells me to test everything and hold onto the good, and to test everything in light of scripture (1 Thessalonians 5:21, Acts 17:11) . Hopefully it plants a seed that they are in a cult that won’t let them examine alternative views.
With Mormons, I focus on Galatians 1:8-9. I ask if their Gospel is the same as Paul’s. If yes, then the rest of their works are redundant. If no, then I should immediately reject it.
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.
CARM.org has great information on both Mormons and Jehovah’s Witnesses.
