The Prophet gave his brethren three grand keys whereby to know whether any supernatural visitor was from God or from Satan.

When a messenger comes, saying he has a message from God, offer him your hand, and request him to shake hands with you. If he be an angel, he will do so, and you will feel his hand. If he be the spirit of a just man made perfect, he will come in his glory; for that is the only way he can appear. Ask him to shake hands with you, but he will not move, because it is contrary to the order of heaven for a just man to deceive; but he will still deliver his message. If it be the devil as an angel of light, when you ask him to shake hands, he will offer you his hand, and you will not feel anything: you may therefore detect him.

In the midst of these exalted labors, Joseph took great delight in mingling with the brethren in manly sports. On Saturday, the 28th day of January, 1843, he played a fine game of ball at Nauvoo with his brethren. During the same winter some of his friends saw him teaching his little son Frederick to slide upon the ice; and the Prophet enjoyed the exhilaration and was as merry as a boy. On Monday, the 13th day of March, 1843, Joseph met William Wall, the most expert wrestler of Ramus, Illinois, and had a friendly bout with him. He easily conquered Wall who up to that time had been a champion. About the same time he had a contest at pulling sticks with Justus A. Morse, reputed to be the strongest man in that region. The Prophet used but one hand and easily defeated Morse.

One evening in March, twenty-seven children were brought to a meeting to be blessed. Joseph took great joy in laying his hands upon the heads of the innocent little ones, and he blessed nineteen of them himself with great fervency. He turned pale and lost his strength, and was compelled to retire, leaving the meeting and its duties to his brethren. Elder Jedediah M. Grant inquired of him the next day concerning the cause of the strange manifestation. The Prophet replied that as he blessed the little ones, it was made known to him that Lucifer would exert an influence to destroy them, and he strove with all his faith to seal upon them security of their lives and virtue upon earth. So much power emanated from him into the children that he became weak. Joseph referred to the case of the woman who touched the hem of the garment of Jesus, by which her issue of blood was staunched, and the Savior said: "Somebody hath touched me; for I perceive that virtue has gone out of me."

Joseph told Elder Grant that the virtue referred to by the Savior was the spirit of life; and men who exercised great faith in administering to the sick, blessing little children, and making confirmations were liable to become weakened.

On Monday, the 6th day of February, 1843, the Prophet was elected mayor of Nauvoo by unanimous vote; at the same time Orson Spencer, Daniel H. Wells, George A. Smith and Stephen Markham were elected aldermen; and Hyrum Smith, John Taylor, Orson Hyde, Orson Pratt, Sylvester Emmons, Heber C. Kimball, Benjamin Warrington, Daniel Spencer and Brigham Young were elected councilors.

Joseph put his accustomed vigor into his duties as chief officer of the municipality. At the first meeting of the council after the election Joseph urged the necessity of relieving the city of unnecessary expenses and burdens, and warned the members against demanding pay for every little service rendered. At the same meeting it was resolved to establish markets in the city; and the Prophet spoke earnestly about the regulation of prices, so that the poor should not be oppressed; that, while the farmer should have fair compensation for his products, the mechanic should also have justice in purchasing the necessaries of life.

If the principles of official integrity and economy, and the principles of fair dealing and mutual protection between producers and dealers, which the Prophet taught at this time, could have general acceptance and obedience throughout the world, what a wonderful stride would be taken toward the social redemption of the human race! Politics would be purified—for only men of integrity and nobility of character could or would hold office. Pauperism, that fruitful source of crime, would be practically unknown. Public economy and private prosperity would go hand in hand.

On the 2nd day of March, 1843, the House of Representatives of the Illinois Legislature took up a bill to repeal a part of the Nauvoo city charter. There was a determination on the part of the majority to push the bill to its passage; and all the protests of a few fair-minded and courageous men availed nothing. Representative Thomas B. Owen compared the charter of Nauvoo with those of other cities and showed that this bill proposed to repeal the same powers in the Nauvoo charter which existed in every other charter in the state. He declared positively of his own knowledge that good order and industry characterized the "Mormons," and he made no doubt that they were much abused. He protested against such a malicious and contemptible course of cowardice as that which was proposed. Next day the bill was put upon its passage; and William Smith of Nauvoo, who was a representative in the Assembly, moved an amendment to the title of the measure so that it would read—"A bill for an act to humbug the citizens of Nauvoo." The motion created great sensation, in the midst of which William declared that he considered the amendment perfectly described the contents of the bill, and he was anxious that things should be called by their right names. Naturally the chair decided that such an amendment, "not being respectful," was not in order, and the bill with its original title was then passed. On the 4th of March the Senate considered this same measure and refused to pass it.

Hyrum brought information to the mayor on the evening of the 25th of March, 1843, upon which Joseph issued a proclamation as follows:
