There are many called but few are chosen, and why are they not chosen? Because their hearts are set upon the things of the world and are aspiring to the honors of men; they do not learn the lesson that the right, of the priesthood, are inseperably connected with the powers of heaven; and that the powers of heaven cannot be controlled nor handled, only upon the principles of righteousness, that they may be confered upon us, it is true, but when we undertake to cover our sins, to gratify our pride, vain ambition, or to exercise dominion or compulsion over the souls of the children of men, in any degree of unrighteousness; behold the heavens withdraw themselves, the Spirit of the Lord is grieved, then amen to the priesthood, or to the authority of that man; behold ere he is aware, he is left to kick against the prick; to persecute the saints, and to fight against God. We have learned by sad experience, that it is the nature and disposition of almost all men, as soon as they get a little authority, as they suppose, to begin to exercise unrighteous dominion, hence many are called but few are chosen. No power or influence can, or aught to be maintained by virtue of the priesthood, only by persuasion, by long suffering, by gentleness, by meekness and by love unfeigned; without hypocracy and without guile: reproving with sharpness when moved upon by the holy Ghost, and afterwards showing forth an increase of love towards him whom thou hast reproved, lest he esteem thee to be his enemy, so that he may know, that thy faithfulnees is stronger than the cords of death. Let the soul be full of charity towards all men, and virtue guard thy confidence wax strong in the presence of God, and the doctrines of the priesthood shall destil upon thy soul, as the dews from heaven; they sceptre shall be an unchanging sceptre of righteousness, the Holy Ghost shall be thy constant companion, thy dominion shall be an everlasting dominion, the ends of the earth shall enquire thy name; fools shall have thee in derision, hell shall rage against thee, while the pure in heart, the wise, the noble, and the virtuous shall seek council, authority, and blessing, constantly from under thy hand: thy people shall never be turned against thee by the testimony of traitors, although their influence shall cast the into trouble, and into prisons, thou shall be had in honor, and but for a small moment, and thy voice shall be more terrible in the midst of thy enemies, than the fierce lion, because of thy righteousness: and thy God shall stand by thee forever and ever.”

"Hearken, O ye elders of my church, and give ear to the voice of the living God; and attend to the words of wisdom which shall be given unto you, according as ye have asked and are agreed as touching the church, and the spirits which have gone abroad in the earth. Behold varily I say unto you, that there are many spirits which are false spirits, which have gone forth in the earth, deceiving the world; and also satan hath sought to deceive you, that he might overthrow you.

Behold I the Lord have looked upon you, and have seen abominations in the church, that profess my name; but blessed are they who are faithful and endure, whether in life on in death, for they shall inherit eternal life. But wo unto them who are deceivers, and hypocrites, for thus saith the Lord, I will bring them to judgment.

Behold verily I say unto you, there are hypocrites among you, and have deceived some, which has given the adversary power, but behold such shall be reclaimed; but the hypocrites shall be detected and cut off, either in life or in death, even as I will, and wo unto them who are cut off from my church, for the same are overcome of the world: wherefore, let every man beware lest he do that which is not in truth and righteousness before me.

And now come, saith the Lord by the spirit, unto the elders of his church, and let us reason together, that ye may understand: let us reason even as a man reasoneth one with another face to face: now when a man reasoneth, he is understood of man, because he reasoneth as a man; even so will I the Lord reason with you that you may understand: wherefore I the Lord asketh you this question, unto what were you ordained? To preach my gospel by the Spirit, even the comforter which was sent forth to teach the truth; and then received ye spirits which ye could not understand, and received them to be of God, and in this are ye justified? Behold ye shall answer this question yourselves, nevertheless I will be merciful unto you: he that is weak among you hereafter shall be made strong.

Verily I say unto you, he that is ordained of me and sent forth to preach the word of truth by the Comforter, in the spirit of truth, doth he preach it by the spirit of truth, or some other way? and if by some other way, it be not of God: therefore, why is it that ye cannot understand and know that he that receiveth the word by the spirit of truth, receiveth it as it is preached by the spirit of truth?

Wherefore, he that preacheth and he that receiveth, understand one another, and both are edified and rejoice togetherand that which doth not edify, is not of God, and is darkness; that which is of God is light, and he that receiveth light and continueth in God, receiveth more light, and that light groweth brighter and brighter, until the perfect day. And again, verily I say unto you, and I say it that you may know the truth, that you may chase darkness from among you, for he that is ordained of God and sent forth, the same is appointed to be the greatest, notwithstanding he is least, and the servant of all: wherefore he is possessor of all things, for all things are subject unto him, both in heaven and on the earth, the life, and the light, the spirit, and the power, sent forth by the will of the Father, through Jesus Christ, his Son, but no man is possessor of all things, except he be purified and cleansed from all sin; and if ye are purified and cleansed from all sin, ye shall ask whatsoever ye will in the name of Jesus , and it shall be done: but know this, it shall be given you what you shall ask, and as ye are appointed to the head, the spirits shall be subject unto you:

Wherefore it shall come to pass, that if you behold a spirit manifested that you cannot understand, and you receive not that spirit, ye shall ask of the Father in the name of Jesus, and if he give not unto you that spirit, that you may know that it is not of God: and it shall be given unto you power over that spirit, and you shall proclaim against that spirit, with a loud voice, that it is not of God; not with railing accusation, that ye be not overcome; neither with boasting, nor rejoicing, lest you be seized therewith: he that receiveth of God, let him account it of God, and let him rejoice that he is accounted of God worthy to receive, and by giving heed and doing these things which ye have received, and which ye shall hereafter receive; and the kingdom is given you of the Father, and power to overcome all things, which is not ordained of him: and behold, verily I say unto you, blessed are you who are now hearing these words of mine from the mouth of my servant, for your sins are forgiven you."

"And righteousness and truth will I cause to sweep the earth as with a flood, to gather out mine own elect from the four quarters of the earth, unto a place which I shall prepare; an holy city, that my people may gird up their loins, and be looking forth for the time of my coming; for there shall be my tabernacle, and it shall be called Zion; a New Jerusalem."
