The Doctrine and Covenants -Doctrine and Covenants – Chapter 17 | Verse 5
The Doctrine and Covenants
And ye shall testify that you have seen them, even as my servant Joseph Smith, Jun., has seen them; for it is by my power that he has seen them, and it is because he had faith.
To see the plates and not testify would be like saying the sun is in the sky and that it is not present, to outright deny the holy god of heaven knowing and being invited in his presence; undertaking his work and then embracing the father of lies.
