Nephi tells us in his record that if we are not pleased with what he has engraved upon the plates, that make up the Book of Mormon, then we are not pleased with God and are not God's people.
"Wherefore, I, Nephi, to be obedient to the commandments of the Lord, went and made these plates upon which I have engraven these things. And I engraved that which is pleasing unto God. And if my people are pleased with the things of God they will be pleased with mine engravings which are upon these plates."
- 2 Nephi 5:31-32
