Revelation, 9 May 1831 [D&C 50]

let us reason even as a man reasoneth one with another  face to face now when a man reasoneth he under[stand]eth 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 ye ordained to  Preach my Gospel by the spirit even the comforter which  was sent forth to teach the truth & then received you spirits  which ye could not understand & received them to be of God  & in this are ye Justified? Behold ye shall answer this  yourselves nevertheles I will be mercyfull unto you he that  is weak among you hereafter shall be made strong verily I  say unto you he that is ordained of me & sent forth to preach  the word of truth by the comforter the spirit of truth doth  he preach it by the spirit of truth or some other way & if by  some other way it be not of God & again he that receiveth the  word of truth doth he receive it by the spirit of truth or  some other way if it be some other way it be not of God therefore  why is it that ye cannot understand & 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 & he that> receiveth understandeth  one another & both are edified & rejoice together & that which  doth not edify is not of God & is darkness that which is of God  is light & he that receiveth light & continueth in god receiveth  more light & that light groweth lighter brighter and brighter untill  the perfect day & again verily I say unto you & I say it that  you may know the truth that you may choose chase darkness  from among you for he that is ordaned of God & sent forth  the same is apponted to be the greatest notwithstanding he  is least & the servent of all wherefore he is possessor of all  things <for all things> are subject unto him both in Heaven & on the Earth  the life & the light the spirit & 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 & cleansed  from all sin & if ye are purified & cleansed from all sin  ye shall ask whatsoever you will in the name of Jesus  & it shall be done but know this it shall be given [p. 83]
In March 1831, JS wrote to his brother Hyrum in New York that he had been engaged in “regulating the Churches” in Ohio because of the presence of what he considered questionable and false spiritual manifestations (Letter to Hyrum Smith, 3–4 March 1831). John Whitmer later remarked in his history that “many would not turn from their folly, unless God would give a revelation.” Urging church members to seek the best gifts, this revelation also warned them to avoid the seduction of “evil spirits.” (Compare Revelation, ca. 8 March 1831–A [D&C 46].)
This text was addressed to the elders of the church, and John Whitmer copied it into Revelation Book 1, where it is designated “52nd Commandment May 9th 1831,” sometime between May and June 1831. Sidney Gilbert and Orson Hyde also recorded copies in revelation notebooks, possibly between June 1831 and early 1832. The 1833 Book of Commandments dates the revelation to May 1831 at Kirtland, Ohio, while the 1835 Doctrine and Covenants gives the same date but no location.
