“And out of the throne proceeded lightnings and thunderings and voices: and there were seven lamps of fire burning before the throne, which are the seven Spirits of God.”
King James Version (KJV)
4:5 And out of the throne go forth lightnings - Which affect the sight. Voices - Which affect the hearing. Thunderings - Which cause the whole body to tremble. Weak men account all this terrible; but to the inhabitants of heaven it is a mere source of joy and pleasure, mixed with reverence to the Divine Majesty. Even to the saints on earth these convey light and protection; but to their enemies, terror and destruction.
Re 4:5 And out of the throne proceeded lightnings and thunderings and voices. These seem to portray the threatenings and judgments which proceed from the throne. And [there were] seven lamps of fire burning before the throne. These bright light-giving lamps symbolize the Holy Spirit in the fulness of its manifestation, indicated by the seven Spirits of God. See PNT "Re 1:4".
