Scriptures mean

1. Alma 12: 21
     21 What does the scripture mean, which saith that God placed cherubim and a flaming sword on the east of the garden of Eden, lest our first parents should enter and partake of the fruit of the tree of life, and live forever? And thus we see that there was no possible chance that they should live forever.
2. D&C 74: 7
     7 But little children are holy, being sanctified through the atonement of Jesus Christ; and this is what the scriptures mean.
3. JS-H 1: 74
     74 Our minds being now enlightened, we began to have the scriptures laid open to our understandings, and the true meaning and intention of their more mysterious passages revealed unto us in a manner which we never could attain to previously, nor ever before had thought of. In the meantime we were forced to keep secret the circumstances of having received the Priesthood and our having been baptized, owing to a spirit of persecution which had already manifested itself in the neighborhood.
