Brigham Young teaches Adam knew he had to partake of the fruit before he came to this earth so he could ascend to "thrones, principalites, and powers."
Brigham Young, "Consecration," Journal of Discourses, 26 vols.(Liverpool: F.D. Richards, 1855), 2:302
In my fullest belief, it was the design of the Lord that Adam should partake of the forbidden fruit, and I believe that Adam knew all about it before he came to this earth. I believe there was no other way leading to thrones and dominions only for him to transgress, or take that position which transgression alone could place man in, to descend below all things that they might ascent to thrones, principalities, and powers; for they could not ascend to that eminence without first descending, nor upon any other principle.
