Revelation, 23 July 1837 [D&C 112]

unto you, I say unto all the twelve. Arise and gird up your loins, take  up your cross, follow me, and feed my sheep. Exalt not yourselves; rebel  not against my servant Joseph for Verily I say unto you I am with  him and my hand shall be over him; and the keys which I have given  him, and also to youward shall not be taken from him untill I come.
Verily I say unto you my servant Thomas, thou art the man whom  I have chosen to hold the keys of my kingdom (as pertaining to the twelve)  abroad among all nations, that thou mayest be thy my servant to un lock the door of the kingdom in all places where my servant Joseph,  and my servant Sidney [Rigdon], and my servant Hyrum [Smith], cannot come, for on  them have I laid the burden of all the Churches for a little season:  wherefore whithersoever they shall send you, go ye, and I will be with  you and in whatsoever place ye shall proclaim my name an effectual  door shall be opened unto you that they may receive my word. Whosoever  receiveth my word receiveth me, and whosoever receiveth me receiveth those  (the first presidency) whom I have sent, whom I have made counsellors  for my name’s sake unto you. And again I say unto you, that who soever ye shall send in my name, by the voice of your brethren the  twelve, duly recommended and authorized by you, shall have power  to open the door of my kingdom unto any nation whithersoever ye shall send  them, inasmuch as they shall humble themselves before me and abide in  my word, and hearken to the voice of my spirit.
Verily verily! I say unto you, darkness covereth the earth and gross  darkness the people minds of the people, and all flesh has become corrupt  before my face! Behold vengeance cometh speedily upon the inhabitants  of the earth. A day of wrath! A day of burning! A day of des olation! Of weeping! Of mourning and of lamentation! And as  a whirlwind it shall come upon all the face of the earth saith the Lord.  And upon my house shall it begin and from my house shall it go forth  saith the Lord. First among those among you saith the Lord; who  have professed to know my name and have not known me and  have blasphemed against me in the midst of my house saith the Lord
Therefore see to it that you trouble not yourselves concerning the  affairs of my Church in this place saith the Lord, but purify your  hearts before me, and then go ye into all the world and preach my gospel  unto every creature who have not received it and he that believeth and  is baptized shall be saved, and he that believeth not, and is not baptized [p. 73]
