Whatever else Revelation is, it is a glimpse of the inexpressible reality of God–a reality that is wholly and completely other than anything we are. He is holy. Twice in scripture, we hear that he is “holy, holy, holy”: here in Revelation, and also in Isaiah, as Isaiah glimpses the same reality.
Isaiah’s response to that glimpse? “Woe is me!” Even partially apprehending who God is leaves us recognizing our own unworthiness. But God, being rich in mercy, comes to us, just as he went to Isaiah, telling us that we are loved. Our response is worship, and the same thing that Isaiah uttered. “Here I am.” All of our worship is witnessing to this rich, merciful grace of God.
And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to say, “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!” (Revelation 4:8)
Almighty God, unto whom all hearts are open, all desires known, and from whom no secrets are hid, cleanse the thoughts of hearts by the inspiration of thy Holy Spirit, that we may perfectly love thee, and worthily magnify thy holy name, through Jesus Christ our Lord. Amen.
