Heard a lesson on The Plan of Salvation (very definitely pronounced with the capitalization) this past Sunday. One of the things that was vectored was the widespread Mormon meme that Satan’s plan, in opposition to God the Father’s plan, was to involve forcing everyone on earth to behave correctly, thus getting everyone back to the presence of the Father sinless and ready to be saved.

Every time i hear this, i think: And this appealed so strongly to one-third of everybody?

There are lots of other possibilities that sound like they’d be more appealing, at least to me (e.g., making sure nobody ever received the laws of God, therefore meaning that everybody would be judged as having not lived under the law, and therefore be ready to be saved), and we certainly don’t know any of the details of Satan’s plan—so why is the one i mentioned in the first paragraph so widely repeated, as if we knew for certain that that’s what it was?
