1 Nephi

And it came to pass that there arose a mist of darkness; yea, even an exceedingly great mist of darkness, insomuch that they who had commenced in the path did lose their way, that they wandered off and were lost.

And it came to pass that I beheld others pressing forward, and they came forth and caught hold of the end of the rod of iron; and they did press forward through the mist of darkness, clinging to the rod of iron, even until they did come forth and partake of the fruit of the tree.

And I said unto them that it was the word of God; and whoso would hearken unto the word of God, and would hold fast unto it, they would never perish; neither could the temptations and the fiery darts of the adversary overpower them unto blindness, to lead them away to destruction.
