4 Nephi 1

37 Therefore the true believers in Christ, and the true worshipers of Christ, (among whom were the three disciples of Jesus who should tarry) were called Nephites, and Jacobites, and Josephites, and Zoramites.

The three of them dwelt with the group. I wonder if they do that today. Like, I wonder if they just attend someone's ward or if they spend most time like missionaries, traveling the globe. I wonder if you would know if you had met them. That would be cool.

38 And it came to pass that they who rejected the gospel were called Lamanites, and Lemuelites, and Ishmaelites; and they did not dwindle in unbelief, but they did wilfully rebel against the gospel of Christ; and they did teach their children that they should not believe, even as their fathers, from the beginning, did dwindle.

This is quite bad. They did believe, but completely did not care. And they taught their children the wrong things. This is serious business.

39 And it was because of the wickedness and abomination of their fathers, even as it was in the beginning. And they were taught to hate the children of God, even as the Lamanites were taught to hate the children of Nephi from the beginning.

I wonder if Laman and Lemuel look back on this and just kick themselves for what they started. Do they feel terrible, or do they still not care?

40 And it came to pass that *two hundred and forty and four years had passed away, and thus were the affairs of the people. And the more wicked part of the people did wax strong, and became exceedingly more numerous than were the people of God.
41 And they did still continue to build up churches unto themselves, and adorn them with all manner of precious things. And thus did two hundred and fifty years pass away, and also two hundred and sixty years.
42 And it came to pass that the wicked part of the people began again to build up the secret oaths and combinations of Gadianton.
43 And also the people who were called the people of Nephi began to be proud in their hearts, because of their exceeding riches, and become vain like unto their brethren, the Lamanites.
44 And from this time the disciples began to sorrow for the sins of the world.

This is the sorrow the prophets must feel from time to time. And yet they do not harden their hearts. That would be the easy route. Not letting things get to you by hardening your heart. A good practice to stay away from being vain about riches is to give away your stuff from time to time. It's fun.
