B. H. Roberts, "Joseph Smith: An Appreciation," Improvement Era 36, no. 2 (December 1932): 81
Frankly I confess myself to be of the first class: one who believes in him, accepts him as a Prophet of the Most High God, inspired as no other man has been inspired to establish God's truth in the world; one who believes in him without reservation. To me he was a mighty spirit which made him one of God's "great" and "noble," and "good" intelligences in his own right, by the very nature of him; he was perhaps second only to the Christ, the Son of God, in that spirit estate preceding earth-life. To this spirit, great, and mighty, and strong, God gave in addition, authority and inspiration which made him of a quick and mighty understanding.
