“One can scarcely imagine such deeply spiritual and profound things being uttered by little children. We are left to conjecture about their messages. Was the veil parted to allow them to speak of life in the first estate? Did they discourse upon life among the Gods in a celestial environment? Did they reveal doctrinal mysteries which today’s world could not receive? … This was such a sacred manifestation, the content of these inspired utterances were of such a nature, that mortal language could not adequately capture the true meaning and intent. In this sense, things of the Spirit are unspeakable (compare 3 Nephi 17:15–18)” (McConkie et al., Doctrinal Commentary, 4:172).
