The seven Spirits which are before the throne of Christ

 

Revelation 1:4...Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne;

In the Hebrew, seven (Sheh'-bah) is from a root word meaning to be complete or full

The seven Spirits before the Throne of Christ referred to the complete and full work of the Holy Spirit that "reveals Christ to the human soul". Perhaps in Prophecy. Perhaps in power or perhaps in Divine Revelation. The Spirit of God revealed Christ to the Prophets in the Old Testament and to the Apostles of the New Testament. The seven Spirits simply referred to the "perfect work of the Spirit of God". 

Divine Revelation from the Spirit of God reveals Christ which is, which was, and which is to come. When John was exiled to the Isle of Patmos the Revelation of Christ was given to his heart and thinking by the complete and perfect work of the Spirit of God. John's understanding of his present situation with the seven Churches also prophetically illustrated a bigger picture concerning the Rapture of the Church and what followed.  The big picture is within the very Throneroom where Christ is exalted at that time. 

One must note "during and after the Rapture the Church" the Omnipresence of the Holy Spirit resides in Heaven with Christ and all the sainted men and women awaiting a return to Earth to establish the 1000 year reign. During the Rapture the Holy Spirit "steps aside" and the Anti-Christ steps in with wickedness on Earth. The Spirit of God will be in Heaven during that seven Year Tribulation on Earth.

While the Holy Spirit is in Heaven with Christ and the saints...prophecy begins to unfold on Earth without the Holy Spirit's Omnipresence during Satan's Kingdom and reign of the Anti-Christ. John's terminology of the seven Spirits before the throne of Christ gives us a glimpse of the magnitude of the Holy Spirit in Heaven during that predicted time of prophecy. Seven in the eyes of Jewish people always makes reference to perfect, perfected, or perfection in the Old Testament records.
