To And From The Seven -Revelation 1:4

Rev 1:4 John, To the seven churches in the province of Asia:

Grace and peace to you from him who is, and who was, and who is to come, and from the seven spirits before his throne

Now John address seven of the churches, or congregations of the true church, and conveys a letter to each one with observations and advice particular to each local body, but from which the body of Christ may learn and take instruction as well.  The number of the churches, seven, implies a completeness and wholeness of message of Christ.

John bears the greeting from God our Father, extending the offer of grace and peace from the great “I AM”.  “I AM” Is another title which contains the ever present and eternal reality of our Creator, expressed in this verse with the three fold expression of is, was, and is to come.

Psalms 84:11 For the Lord God is a sun and shield;

the Lord bestows favor and honor;

no good thing does he withhold

from those whose walk is blameless

Seven is also used to signify the spirits before His throne.  This could be a reference to the passage in Isaiah which speaks of a seven fold description of the Spirit that would rest on Jesus, and therefore available to all believers. 

Isaiah 11:2 The Spirit of the Lord will rest on him—

the Spirit of wisdom and of understanding,

the Spirit of counsel and of might,

the Spirit of the knowledge and fear of the Lord

Revelation 20:11 Then I saw a great white throne and him who was seated on it. The earth and the heavens fled from his presence, and there was no place for them

There is one throne for there is one God.  He is pure and holy.  Only those who are cleansed by the blood of Christ can stand before Him.
