D&C 39

 James  Covel, a method minister for 40 years was promised - 

 "...behold, the days of thy deliverance are come, if thou wilt hearken to my voice, which saith unto thee: Arise and be baptized, and wash away your sins, calling on my name, and you shall receive my Spirit, and a blessing so great as you never have known.

11 And if thou do this, I have prepared thee for a greater work. Thou shalt preach the fulness of my gospel, which I have sent forth in these last days, the covenant which I have sent forth to recover my people, which are of the house of Israel.

12 And it shall come to pass that power shall rest upon thee; thou shalt have great faith, and I will be with thee and go before thy face.

13 Thou art called to labor in my vineyard, and to build up my church, and to bring forth Zion, that it may rejoice upon the hills and flourish.

14 Behold, verily, verily, I say unto thee, thou art not called to go into the eastern countries, but thou art called to go to the Ohio.

15 And inasmuch as my people shall assemble themselves at the Ohio, I have kept in store a blessing such as is not known among the children of men, and it shall be poured forth upon their heads. And from thence men shall go forth into all nations."  (Doctrine and Covenants 39:10–15)

But He chose to walk away.
