. . . 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.
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.
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.
- D&C 39:11-13
