In Moroni, chapter 7, Mormon talks about the nature of good and evil:
“Wherefore, all things which are good cometh of God; and that which is evil cometh of the devil . . . ” (v. 12)
So, I wonder then if we can consider Christian churches other than the Church of Jesus Christ of Latter-day Saints to be from God, presuming of course that they are (inherently) good. I think that many, if not all, of them are good. Many of them put a lot of money and resources into humanitarian efforts, for example. Some of them led the way for the Restoration. Which actually brings us to another question that came to my mind.
If the Jehovah’s Witnesses church is good, and thus God played some role in its development (it “cometh from God”), how does that fit into the fact that it was not established until at least 40 years after the Mormon Church? Why would God influence a post-Restoration church after his “only true and living church” (D&C 1:30) was established? For that matter, why would he influence more than one (Seventh-day Adventist, Pentecostals, etc).
Unless of course the Jehovah’s Witnesses church isn’t good, or cometh of God means something very vague.
