This episode is about Satan and how much he wants to stop God’s work from progressing. But never fear, the Lord’s “wisdom is greater than the cunning of the devil.”
From the manual:
As the translation of the Book of Mormon progressed, a question naturally arose: What should Joseph Smith and Oliver Cowdery do about those pages of the translation that had been lost? The logical thing might be to go back and retranslate that portion, but the Lord could see something that they could not—wicked men were plotting to alter the words on those pages to cast doubt on Joseph’s inspired work. God had a plan to thwart Satan’s efforts and compensate for what was lost. This plan was put into motion thousands of years earlier when the prophet Nephi felt inspired to create a second record that covered the same time period. Later, Mormon was inspired to include this record in the Book of Mormon “for a wise purpose” known to the Lord (see Words of Mormon 1:3–7).
“My wisdom,” the Lord said to Joseph, “is greater than the cunning of the devil” (Doctrine and Covenants 10:43). That’s a reassuring message in a day like ours, when the adversary’s ongoing efforts to weaken faith are intensifying. Like Joseph, we can be “faithful and continue on” in the work God has called us to do (verse 3). Then we will find that He has already provided a way so that “the gates of hell shall not prevail” against us (verse 69).
See Saints, 1:51–61.
