Everyone has the light of Christ

Alma 18
This is the chapter where Lamoni thinks that Ammon is the Great Spirit coming to punish him and his people for their sins. I thought this was interesting because I usually think of Lamanites as being heartless people who didn't really know the difference between right and wrong. But here it shows that they do know. Lamoni is worried that he will be punished for his sins and later he says that it was the traditions of his Fathers to do whatever you want and it's all good. You can basically do no wrong. But Lamoni has the light of Christ and he knew better than to do the things he was doing. Why else would he be so worried about the Great Spirit coming to punish him?
We all have the Light of Christ in our hearts. We all know what is right and what is wrong. We need to follow those promptings and chose the better part.
