'Seven Spirits of God' in the Bible

"And write [this] to the angel of the church at Sardis: These are the words of Him who has the seven Spirits of God [i.e., Jesus, who has the Holy Spirit] and the seven stars [i.e., the seven angels of the seven churches. See 1:20]: I know about your deeds, that you have a reputation for being [spiritually] alive, but you are [really] dead.

And lightning flashes and [loud] sounds of rolling thunder came out of God's throne. And there were seven lighted torches burning in front of the throne, which are the seven Spirits of God [i.e., the Holy Spirit. See 1:4].

Then I saw a Lamb, looking like it had been killed. He was standing in the center of the throne, surrounded by the four living beings and the [twenty-four] elders. He has seven horns and seven eyes, which are the seven Spirits of God [i.e., the Holy Spirit. See 1:4], sent throughout the entire earth.
