As he recounts (somewhere around 588-570 B.C.) how his son Jacob had come to know Christ, Lehi focuses on the power and consistency of the Spirit, who is the third member of the Godhead, in testifying of Christ.
“…I know that thou art redeemed, because of the righteousness of thy Redeemer; for thou hast beheld that in the fulness of time he cometh to bring salvation unto men. And thou hast beheld in thy youth his glory; wherefore, thou art blessed even as they unto whom he shall minister in the flesh; for the Spirit is the same, yesterday, today, and forever.” (2 Nephi 2:3-4)
-Did the Spirit have the power to testify of Christ in ancient times, before He came to the earth? Was the Spirit’s testimony in any way vague or indirect? Or, was it a clear manifestation without ambiguity?
-Is it possible for us, who live after Christ’s coming, to receive a clear manifestation, without ambiguity, that He was (and is) who He said He was?
