FAIRLDS has a nice blog series on the new book about Hugh Nibley. Here's the link to a post by Jeffrey Bradshaw that I highly recommend.
The excerpt below explains how people in Africa, and by extension people everywhere in the world, can relate to the universal themes in the Book of Mormon.
I hadn’t anticipated such great interest in the Book of Mormon in the heart of Africa — after all, I had not thought this was “their” story in the same way it was the story of many indigenous groups in the Americas and the Pacific islands. But we soon found out we were mistaken: the stories of continual violence, wars, and conflicts, endemic corruption, government leaders on the take, Gadianton robbers and assassins, courageous Christians, life-changing visions from heaven, and the Gospel being preached to the poor and poor in heart were indeed their stories, too — and it struck them to the heart to read them. After having lived in the Congo, many of the Book of Mormon stories became daily reality — as they are becoming reality in too many parts of the world.
This is another example of the important principle that Elder Christofferson taught in April 2020.
"The Book of Mormon is the possession of mankind."
