"When I awoke that morning I was a man, although only [still] a boy. There was not anything in the world that I feared [after that]. I could meet any man or woman or child and look them in the face, feeling in my soul that I was a man every whit. That vision, that manifestation and witness that I enjoyed at that time has made me what I am, if I am anything that is good, or clean, or upright before the Lord, if there is anything good in me. That has helped me out in every trial and through every difficulty" (Gospel Doctrine, 5th ed. [1939], 542–43).

The core of that meaningful dream is found in the reproof given by Joseph Smith to young Joseph F. Said the Prophet, "Joseph, you are late."
Replied Joseph F., "Yes, but I am clean—I am clean!"

The result of that dream was that a boy was changed into a man. His declaration "I am clean" gave him self-assurance and courage in facing anyone or any situation. He received the strength that comes from a clear conscience fortified by the approbation of the Prophet Joseph.

This prophetic dream holds something for every man and boy assembled in this vast congregation tonight. It is an old saying among us that "cleanliness is next to godliness."

But when I review the performance of this people in comparison with what is expected, I am appalled and frightened. Iniquity seems to abound. The Destroyer seems to be taking full advantage of the time remaining to him in this, the great day of his power. . . . I have the feeling that the good earth can hardly bear our presence upon it. . . . The Brethren constantly cry out against that which is intolerable in the sight of the Lord: against pollution of mind, body, and our surroundings.

To remain clean and worthy, one must stay positively and conclusively away from the devil's territory, avoiding the least approach toward evil. Satan leaves his fingerprints.
