Times and Seasons (15 Jan 1842): "Christopher Columbus...the discovery of America—the land of Joseph—a land more blessed of the Lord than any other land"
Yea, it was because of this decree that Christopher Columbus, a native of Genoa, an obscure individual, was blessed with a largeness of mind which disdained to confine itself to the old beaten track, and was inspired to contend for eight years with the learned ignorance of the courts and councils of Europe, when (after many a fruitless struggle,) a small fleet was fitted out consisting of three small vessels, and placed under his command, which sailed from spain in 1492, under the patronage of Ferdinand and Isabella then on the united thrones of Castile and Arragon, which terminated in the discovery of America—the land of Joseph—a land more blessed of the Lord than any other land “for the precious things of Heaven, for the dew, and for the deep that coucheth beneath, and for the precious fruits brought forth by the Sun, and for the precious things put forth by the Moon, and for the chief things of the ancient mountains and for the precious things of the lasting hills, and for the precious things of the earth and the fullness thereof.”
And be it known unto you, O ye Gentiles, that this Columbus was inspired by the Almighty Jehovah to make this discovery, that the poor and meek of the earth, and the persecuted and oppressed of all nations might have a place to which they could fly and be secure from the iron grasp of poverty, wretchedness and want, and from the cruel unrelenting hand of the oppressor. And when in process of time the tyrants of the Eastern World began to extend their oppressions unto this land, God raised up a Washington and inspired him to resist their oppression and by the strong arm of military power to maintain and defend the rights of the American colonies as free and independent States, and after the definitive treaty was finally signed and the American colonies were acknowledged free and independent States by all the European powers, and the Commissioners, who were the sages of this government, assembled from the different States and met at Philadelphia on the memorable 10th of May 1787, for the purpose of organizing the General Government, God inspired them to frame the American Constitution so as thereby to establish the rights of man upon the broad basis of civil and religious liberty, that here might forever be found an asylum for the oppressed of all nations  to flee unto for refuge and protection from the power of their oppressors.
Note that Columbus never reached the United States; he was confined to Mexico and Caribbean.
