I was asked recently.
“Who can become a seer?”
I answered this: You could probably substitute “seer” for “prophet” in Moses’ lament: “Would to God all men were [seers]”. The purpose of seership is the same as any other gift of the Spirit: to acquire knowledge of truth. And, assuming “God giveth liberally to all men,” as James promised us, it would follow this was among the things He intended all men to experience.
Read the description of the conditions of post-mortal residence in the presence of God given in Section 130. The “seership” experience there is commonplace. The “sea of glass,” or earth on which they dwell is a great Urim and Thummim, as well as the “white stone” given to them. The result is that ALL occupants of that sphere are seers. Accordingly, we should assume that we obtain our first instructions here to prepare us for living there. Seership, being necessary for life there, is something we ought to expect to be included in the Lord’s tutelage while we are all here.
ALL of us are to “covet the best gifts” on the one hand; and on the other “there is no gift greater” than seership. (That’s Paul and Ammon being quoted.) It follows necessarily, therefore, that we should be seeking to have some experience with this gift here in mortality.
