Mormon Doctrine, pg. 717; “ESTABLISHMENT OF THE AMERICAN NATION. — We know by revelation that the United States was established as a nation by the Lord for two chief reasons: 1. So that the Book of Mormon, containing as it does the fulness of the gospel, might come forth with its message of salvation to both Jew (which includes the Lamanites) and Gentile. 2. So that the Lord’s true Church might be set up again on earth, and thus have the way opened up for the fulfilling of the covenants made by the Lord with the house of Israel.”
Proverbs 25:26; “A righteous man falling down before the wicked is as a troubled fountain, and a corrupt spring.”
I am certain the US didn’t come into existence for the Book of Mormon, how silly and arrogant to even think such a thing. And it definitely didn’t wasn’t founded so Smith could lie to a bunch of people.
