On the other hand, perhaps Joseph Smith was simply fulfilling the promise that Jesus made to His disciples:
11 Believe me that I am in the Father, and the Father in me: or else believe me for the very works sake.
12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
14 If ye shall ask any thing in my name, I will do it. (John 14:11-14)
