2 Nephi 26

 Nephi teaches how the Savior manifests Himself to us writing - 

"...he manifesteth himself unto all those who believe in him, by the power of the Holy Ghost; yea, unto every nation, kindred, tongue, and people, working mighty miracles, signs, and wonders, among the children of men according to their faith."  (2 Nephi 26:13)

It becomes clear that His method of manifestation is through the Holy Ghost.
