In the opening chapter of Mosiah, one of the striking ideas raised is that even Lehi would have forgotten to instruct his people about many important truths, if they had not been written down.
Book of Mormon, Mosiah 1:1-5
Last spring I had some time to wander through several areas of Utah's remote deserts. Several times I stopped to look at petroglyphs and rock paintings left by some unknown people ages ago. Some of the figures are suggestive of the familiar, but most of them are only vaguely recognizable at best. It takes a bit of imagination to try to project meaning into these images. Who can guess what the artist was trying to communicate?

Our translations of the scriptures are testimony of King Benjamin's prophetic wisdom. I think it is no coincidence that the publication of scriptures corresponds exactly with the advent of the greatest epochs of expanding human knowledge over the course of history. If it isn't written down and available for study, it will all too soon be forgotten.
