Rev. 1:4-6 opens the book with what I call a “triple trinity.” First of all, there is a “trinity” of persons; the Father (the one who is, was, and is to come; perhaps a fourth trinity in the larger scheme of the passage), the Holy Spirit (represented by the seven spirits), and Jesus Christ. Jesus Christ is mentioned last because He is the subject of the next two “trinities.”
Next comes a trinity of historical realities that qualify Jesus for the role He plays in Revelation. He is the one who died (He is the faithful witness/martyr—Greek: martus), rose (the “firstborn of the dead”), and has already joined the Father on His throne (“ruler of the kings of the earth”). The death and resurrection of Jesus provide the foundation of His heavenly reign.
The final “trinity” is a trinity of actions. Jesus loves us (Greek present tense), has freed or washed (two different Greek words sound the same, but are one letter different) us from our sins by His blood, and made us a kingdom and priests to God. These actions are all directed toward His people. The ultimate outcome of Jesus’ love, as expressed in His death and resurrection, is to raise His people to the highest possible status; kings and priests.
This “triple trinity” underlines the central theme of the book of Revelation. It is the “revelation of Jesus Christ.” He is THE ONE who died, rose, and now rules the heavens and the earth. These together are the decisive events that change everything in the cosmic conflict. The last trinity summarizes the things that Jesus does particularly for the human race.
