Our current emphasis on Theology Thursdays is the Trinity in the book of Revelation.
Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me. The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne. He who has an ear, let him hear what the Spirit says to the churches.
We again see explicit reference to the three persons of the Godhead, just as we saw in Revelation 1:4-5. It is the Son who is now knocking and inviting us to commune with him and rule with him. It is the Son who is now ruling with the Father. It is the Spirit who is speaking these words of the Son to the church.
It is an awesome invitation that Jesus wants to be with us as we go through each day. Jesus is available to you so that you can conquer temptation and overcome evil with good. It is Jesus who will confess your name before his Father (Rev 3:5). The Jesus who is for you now will be for you forever. Depend on him. Pray now and confess your weakness (Rev 3:17). Ask Jesus to give you strength.
In response to the distinction of persons in Revelation 3:21, modalism claims that it is foolish to think the Son and the Father will sit together on one throne. Therefore, there can only be one person who manifests himself at different times in different ways. Modalism claims there is only one person who is God and modalism denies there are three persons in the Godhead. Is the idea of the Father and Son sitting together on one throne foolish and therefore worthy of our rejection?
If you reject the unity of the Father and Son on the throne as foolishness then you must also reject your unity with the Son on his throne as foolishness. Read Revelation 3:21 again.
The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne.
Instead of repudiating the Trinity, this verse wonderfully teaches the unity of persons. Our unity with the Son (see Romans 6) is a picture in miniature of the unity of the Father and Son. To demand that Revelation 3:21 says Jesus is sitting on the Father’s lap is to demand that Revelation 3:21 says Christians will sit on the Son’s lap. That is not the point! The point is shared rule in perfect unity. John is not describing the seating chart of heaven but the unity of rule over all creation. United to Christ, we are invited into the splendor of the Trinity.
