Revelation 1:

4 This letter is from John to the seven churches in the province of Asia.

Grace and peace to you from the one who is, who always was, and who is still to come; from the sevenfold Spirit before his throne; 5 and from Jesus Christ. He is the faithful witness to these things, the first to rise from the dead, and the ruler of all the kings of the world.
