In Revelation 1:8 we read,
"I am the Alpha and the Omega," says the Lord God, "who is, and who was, and who is to come, the Almighty."
This clearly says that God is yet to come.
In Revelation 11:17 (after the seventh trumpet has been sounded) we read,
We give thanks to you, Lord God Almighty, The one who is and who was because you have taken your great power and begun to reign.
This scripture clearly says that God has come.
In Revelation 16:5 we read
You are just in these judgments, you who are and who were, the Holy one.
This implies to me that God has come
My question is, if God does not begin to reign until after the seventh trumpet, what does, "you who are and who were," mean?
