Creation through the reign of conscience, on to the period of law, the Spirit
worked among men upon occasion, convincing of sin, revealing the will of God,
fitting for specific service to be rendered to God; but that was all.
Pentecost, however, was a fulfillment of the prophecy in Joel. Peter, speaking
to the assembled crowd concerning the sights which they had seen and the sounds
which they had heard, said, in answer to a criticism from some in that crowd:
“Ye men of Judea, and all ye that dwell at Jerusalem, be this known unto you, and give ear unto my words. For these are not drunken, as ye suppose; seeing it is but the third hour of the day; but this is that which hath been spoken by the prophet Joel.”
