John writes in Revelation 1:4-5, “Grace to you and peace from him who is and who was and who is to come, and from the seven spirits who are before his throne and from Jesus Christ”.
John speaks of the Father, the Holy Spirit and Jesus. The goal of their revelation is: grace and divine peace.
The seven spirits or: “the sevenfold spirit” remind of Isaiah 11:2: “And the Spirit of the Lord shall rest upon him, the Spirit of wisdom and understanding, the Spirit of counsel and might, the Spirit of knowledge and the fear of the Lord.”
The spirit has seven names: the spirit of Yahweh, of wisdom, of understanding, of counsel, of might, of knowledge, and of the fear of God.
Seven again means a full whole. The Holy Spirit in all its fullness.
It is important to John that we first see that the Revelation is about divine grace and peace. God is trying to win back lost human beings for a life with him.
