So much could obviously be discussed about Lehi’s vision of the tree of life (and Nephi’s vision that follows it), that it’s difficult to know what to single out. The very phenomenon of prophetic dreams is an interesting one; the Lord has most certainly used them as a means of revelation, as to Lehi here (and in 1 Nephi 2:1), or to Joseph, Pharaoh or even to Nebuchadnezzar in the Bible. For some people that seems to be the principle means by which they get such revelation. Most of my dreams are from a more mundane source.
One part does stick out:
And after they had partaken of the fruit of the tree they did cast their eyes about as if they were ashamed.
And I also cast my eyes round about, and beheld, on the other side of the river of water, a great and spacious building; and it stood as it were in the air, high above the earth.
And it was filled with people, both old and young, both male and female; and their manner of dress was exceedingly fine; and they were in the attitude of mocking and pointing their fingers towards those who had come at and were partaking of the fruit.
And after they had tasted of the fruit they were ashamed, because of those that were scoffing at them; and they fell away into forbidden paths and were lost.
These people had clung to the rod of iron, made their way to the tree, and tasted of the tree of life and its goodness. But they still fell away, because of shame at the mocking of those in the great and spacious building.
Mockery is in great fashion at present, including in both political and religious discussions. It’s certainly a very effective rhetorical tool. But it is not one that establishes truth. You don’t need truth to win an argument with mockery. You just need enough people to jeer with you, and the targets to feel ashamed. And shame can drive people away from things they know to be good.
There’s not much that can stop the mockery of the great and spacious building: that’s left to the Lord’s timing. But in the meantime, I guess we’re in the situation Nephi describes a little later, when others (and the ‘we’ and ‘me’ suggests it includes Nephi) had made their way to the tree of life. Nephi states that others who had entered the building ‘did point the finger of scorn at me and those that were partaking of the fruit also; but we heeded them not’ (1 Nephi 8:33). We too have to somehow not pay attention to such mocking voices, especially when they’re trying to make us ashamed of something that we know to be good and true. We need to be true to God and our better selves, and to ignore the heckling crowd.
