"The spiritual gift of prophecy is quite different. As we read in the Book of Revelation, “The testimony of Jesus is the spirit of prophecy.” (Rev. 19:10.) The Prophet Joseph Smith relied on this scripture in teaching that “every other man who has the testimony of Jesus” is a prophet. (Teachings, p. 119.) Similarly, the Apostle Paul states that “he that prophesieth speaketh unto men to edification, and exhortation, and comfort.” (1 Cor. 14:3.) Thus, in the sense used in speaking of spiritual gifts, a prophet is one who testifies of Jesus Christ, teaches God’s word, and exhorts God’s people. In its scriptural sense, to prophesy means much more than to predict the future" ("Spiritual Gifts," BYU Women's Conference, March 28, 1986).
