These additional powers [second anointing] include all the keys that belong to the holy priesthood on the earth, or were ever revealed to man in any dispensation, and which admit men and women within the veil. They enable them to pass by the angels and the gods, until they get into the presence of the Father and the Son. They make of them kings and priests, queens and priestesses to God, to rule and reign as such over their posterity and those who may be given to them by adoption, in the great jubilee of rest which is near at hand. It gives them the right to the tree of life, and the "seal of the living God in their foreheads," spoken of by John the revelator.
