I ran across the following devotional after being asked a question about the first vision and thought it was interesting enough to share. Several snippets:
Visions can take various forms. Personal visitations or appearances of deity, angels, or even Satan and his emissaries certainly come under the heading of visions. Visions can also include seeing vivid images where the veil is lifted from an individual’s mind in order to see and comprehend the things of God. Certain dreams could be considered visions, particularly when heavenly or spiritual messages are conveyed. Finally, certain revelations received through the Urim and Thummim mediums such as the Nephite interpreters and the seer stone may also be classified as visions.
While the visions received by Joseph Smith were also revelatory experiences, revelations were not always visionary. Hence, in researching Joseph Smith’s visions, I attempted to distinguish between visions and other kinds of inspiration or revelation. More often than not, when a vision was involved, the wording of the source material indicated that a vision–not a more general “revelation”–had been received. However, in some instances, the visual nature of the experience was not quite clear.
Three major points became apparent as I researched Joseph Smith’s visions. First, and perhaps most remarkable, is the sheer number of visions the Prophet received. The majority of these visions are not found in the standard works but pervade the Prophet’s own history and the records kept by contemporaries who were present when a vision was received or when Joseph Smith spoke about his sacred communications. As I began collecting the accounts of the visions, I realized that any attempt to total the number of visions would risk excluding some, since evidence of visions relies upon documentation, and some visions may have been purposely unrecorded. Of one vision Joseph remarked, “I could explain a hundred fold more that I ever have of the glories of the kingdoms manifested to me in the vision were I permitted, and were the people prepared to receive them.”
Second, the Prophet was privileged to receive so many visions that is appears they became almost commonplace experiences for him. For example, in 1843 he said, “It is my meditation all the day, and more than my meat and drink, to know how I shall make the Saints of God comprehend the visions that roll like an overflowing surge before my mind.” Perhaps because his visionary experiences were so frequent, he often left out details or failed to record certain events altogether.
Finally, in a number of instances, others witnessed Joseph Smith’s visionary experiences or were present when the Prophet had visions, often seeing the manifestation with him. The recorded statements of these witnesses and co-participants give additional testimony and credibility to the reality of the Prophet’s seeric experiences.
