Hundreds of years before the Holy Spirit was poured out on the early church on the day of Pentecost, the Old Testament prophet Ezekiel, newly anointed as a priest, got a free preview of how God would send the Holy Spirit to empower His people. The preview came in the form of a Technicolor vision that included a stormy wind, a cloud that glowed with fire, flashes of lightning and strange, four-faced cherubim that were empowered by God's divine energy.
Ezekiel wrote of these heavenly creatures: "In the midst of the living beings there was something that looked like burning coals of fire, like torches darting back and forth among the living beings. The fire was bright, and lightning was flashing from the fire. And the living beings ran to and fro like bolts of lightning" (Ezekiel 1:13-14, NASB).
