Thou must preach the Gospel of thy Savior to the inhabit — inhabitants of the earth, Thou shalt be¬ come a mighty man in the Earth — Thou shalt have great faith — even like that of the Brother of jared. — thou shalt have power to translate thyself from one plannet [planet] to annother [another] — power to go to the moon if thou shalt desire it. Power to preach to the spirits in prison — power like Enoch to translate thyself to heaven, — thou shalt have power to rend the vail [veil] of heaven and see Jesus standing at the right hand of his Father. Theare [There] shall not be a mightier man on Earth than thou. Thy faith shall in-crease and grow stronger and stronger it shall be liken like that of Peter thy shadow shall restore the sick — the diseased shall send to thee their handkerchiefs and aprons and by thy touch their owners shall be healed. Thou shalt have power over unclean spirits; at thy command the powers of darkness shall stand back, and Devils shall flee away. If it be expedient the Dead shall rise and come forth at thy bid[d]ing even those that have long slept in the dust shall come foarth [forth] to life.
