'Seven Spirits of God' in the Bible

“To the angel (divine messenger) of the church in Sardis write:“These are the words of Him who has the seven Spirits of God and the seven stars: ‘I know your deeds; you have a name (reputation) that you are alive, but [in reality] you are dead.

From the throne came flashes of lightning and [rumbling] sounds and peals of thunder. Seven lamps of fire were burning in front of the throne, which are the seven Spirits of God;

And there between the throne (with the four living creatures) and among the elders I saw a Lamb (Christ) standing, [bearing scars and wounds] as though it had been slain, with seven horns (complete power) and with seven eyes (complete knowledge), which are the seven Spirits of God who have been sent [on duty] into all the earth.
