According to John Heinerman, the problem with the F.A.R.M.S. article is that it looks at a spiritually generated procedure from an entirely secular point of view. No one has ever considered the priesthood virtue emanating from our Lord constantly as being the TRUE SOURCE for the stones' continuous illumination. Now this virtue is an interesting thing to explore, for it sheds a great deal of understanding on how light came to be in otherwise dull rocks. The Prophet Joseph Smith, who felt this light or power often in his own life, referred to this peculiar virtue of the priesthood as "the spirit of life." It would leave while blessing little children sometimes; and a small portion of it certainly left our Lord when the woman with the blood issue touched the hem of Jesus' garment and was promptly made whole again (Matthew 9:20).
The virtue of the holy priesthood has been described in different ways by those who've felt it surging through their own bodily systems on various occasions. In his autobiography, Apostle Orson F. Whitney mentioned it "ran like liquid flame to the very tips of my fingers," while in the act of administering to a sick sister, who was instantly healed the moment it surged into her own body from his.
Consider what happened in ancient times with the Old Testament prophet Elisha. He was a man obviously filled with a great deal of this eternal priesthood element in life, as evidenced by the many great miracles he performed for others. Upon his death, as written in 2 Kings 13:20-21, his body was entombed in the usual sepulcher reserved for such purposes. In time, the elements of nature claimed the flesh of his corpse, leaving only the skeletal remains behind. Now a band of marauding Moabites had invaded the land "at the coming in of [a certain] year." One of their number was slain and in making a hasty retreat "they cast the [dead] man into the sepulcher of Elisha; and when the man was let down, and touched the bones of Elisha, he revived and stood on his feet" on account of the priesthood virtue which still remained in the prophet's weathered bones.
