Joseph Smith is pointing out the facts, and they are so true.

I have more to boast of than any man had. I am the only man that has ever been able to keep a whole church together since the days of Adam. A large majority of the whole have stood by me. Neither Paul, John, Peter, nor Jesus ever did it. I boast that no man ever did such work as I (History of the Church, Vol.6, pp. 408-09).
