There is something remarkable about the ministry of the Prophet Joseph Smith. There is certainly an instance of him healing many of the saints after his escape from liberty jail in Missouri. But that was well along into his ministry as a prophet.
What stands out as remarkable is that the signs that followed Joseph Smith, his evidence that he was a prophet, were the truths that he taught.
Every statement of pure truth carries with it the testimony of its truthfulness.
When men were accusing Joseph Smith of being a fallen prophet, what evidence did he give that he was not?
The evidence he gave was his teaching. He opened the windows of heaven for them with knowledge that they could not deny came from God. While this is evident in and of itself, it is made perfectly clear by the Prophet himself. I conclude with his own words:
I want to ask this congregation, every man, woman and child, to answer the question in their own heart, what kind of a being God is? Ask yourselves; turn your thought into your hearts, and say if any of you have seen, heard, or communed with him. This is a question that may occupy your attention for a long time. I again repeat the question–What kind of a being is God? Does any man or woman know? Have any of you seen him, heard him, or communed with him? Here is the question that will, peradventure, from this time henceforth occupy your attention. The Scriptures inform us that “This is life eternal that they might know thee, the only true God, and Jesus Christ whom thou hast sent.”
If any man does not know God, and inquires what kind of a being he is,–if he will search diligently his own heart–if the declaration of Jesus and the apostles be true, he will realize that he has not eternal life; for there can be eternal life on no other principle.
My first object is to find out the character of the only wise and true God, and what kind of a being he is; and if I am so fortunate as to be the man to comprehend God, and explain or convey the principles to your hearts, so that the Spirit seals them upon you, then let every man and woman henceforth sit in silence, put their hands on their mouths, and never lift their hands or voices, or say anything against the man of God or the servants of God again.
