"Boys, I am a Prophet. I am not a saint."
Now that, that is my kind of religious leader. 
God made Aaron to be the mouthpiece of the children of Israel, and he will
make me to be god to you in his stead, and the elders to be mouth for me;
and if you don't like it, you must lump it. Joseph Smith, Jr., Nauvoo, Illinois
April, 1844
Another good example of his eloquent leadership, IMHO.

"He (Joseph Smith) is the man through whom God has spoken... yet I would not like to call him a savior, though in a certain capacity he was a god to us, and is to the nations of the earth, and will continue to be."
- Brigham Young, Journal of Discourses 8:321
"You call us fools; but the day will be, gentlemen and ladies, whether you belong to this Church or not, when you will prize brother Joseph Smith as the Prophet of the Living God, and look upon him as a god..."
- Herber C. Kimball, Journal of Discourses 5:88
"If we get our salvation, we shall have to pass by him [Joseph Smith]; if we enter our glory, it will be through the authority he has received. We cannot get around him [Joseph Smith]"
- (as quoted in 1988 Melchizedek Priesthood Study Guide, p. 142)
There is "no salvation without accepting Joseph Smith. If Joseph Smith was verily a prophet, and if he told the truth...no man can reject that testimony without incurring the most dreadful consequences, for he cannot enter the kingdom of God"
- Joseph Fielding Smith, Doctrines of Salvation, vol. 1, p.190
"I tell you, Joseph holds the keys, and none of us can get into the celestial kingdom without passing by him. We have not got rid of him, but he stands there as the sentinel, holding the keys of the kingdom of God; and there are many of them beside him. I tell you, if we get past those who have mingled with us, and know us best, and have a right to know us best, probably we can pass all other sentinels as far as it is necessary, or as far as we may desire. But I tell you, the pinch will be with those that have mingled with us, stood next to us, weighed our spirits, tried us, and proven us: there will be a pinch, in my view, to get past them. The others, perhaps, will say, If brother Joseph is satisfied with you, you may pass. If it is all right with him, it is all right with me. Then if Joseph shall say to a man, or if brother Brigham say to a man, I forgive you your sins, "Whosoever sins ye remit they are remitted unto them;" if you who have suffered and felt the weight of transgression—if you have generosity enough to forgive the sinner, I will forgive him: you cannot have more generosity than I have. I have given you power to forgive sins, and when the Lord gives a gift, he does not take it back again."
- Orson Hyde, Journal of Discourses, Vol. 6, p.154-155
"It is because the Lord called Joseph Smith that salvation is again available to mortal men.... If it had not been for Joseph Smith and the restoration, there would be no salvation,"
- Bruce McConkie, Mormon Doctrine, p. 396, 670
