11. I, Joseph, the prophet, in spirit beheld,
And the eyes of the inner man truly did see
Eternity sketch’d in a vision from God,
Of what was, and now is, and yet is to be.
12. Those things which the Father ordained of old,
Before the world was, or a system had run,—
Through Jesus the Maker and Savior of all;
The only begotten, (Messiah) his son
. . .
18. And now after all of the proofs made of him,
By witnesses truly, by whom he was known,
This is mine, last of all, that he lives; yea he lives!
And sits at the right hand of God, on his throne.
19. And I heard a great voice, bearing record from heav'n,
He's the Saviour, and only begotten of God-
By him, of him, and through him, the worlds were all made,
Even all that career in the heavens so broad,
20. Whose inhabitants, too, from the first to the last,
Are sav'd by the very same Saviour of ours;
And, of course, are begotten God's daughters and sons,
By the very same truths, and the very same pow'rs.
