Vision, 16 February 1832 [D&C 76]

But great and marvelous are the works of the Lord  and the mistries of his kingdom which he shewed  unto us which surpasseth all understanding in glory  and <in> might and in dominion which he commanded  us we should not write while we were yet in the  spirit and are not lawful for men to utter neither  is man capable to make them known for they  are only to be seen and understood by the power  of the holy ghost which God bestows on those who  love him and purifies themselves before him to  whom he grants the privalege of seeing and knowing  for themselves that through the power and manifestation  of the spirit while in the fless [flesh] they may be able  to bear his presence in the world of glory and to  God and the Lamb be glory and honor and dominion  for ever and ever Amen
