Rebellious,
Here would be by questions to the Witnesses on the great crowd. Where does the Book of Revelation say that the throne and the Lamb (Jesus) are located? See Rev. 4:4-5, Rev. 5:6-7, 11-14 Is not the throne and the Lamb in heaven? Now where does Rev. 7:9-10 put the great crowd if not before the throne and the Lamb? And where are the angels if not also before the throne? vs. 11-12 How is that different from Rev. 19:1. See also verses 4-6. If God and his throne and the Lamb are now in heaven (Col. 3:1-2), then the great crowd will be there also.
Here's my take on the Word.. Was there ever a time that God was "speechless?" Gen. 1 portrays God as "speaking" in the beginning. See verses 3, 6, etc. Does that mean that God never "spoke" before? That he was mute until he "spoke" creation into being? Or has God had a "voice" from all eternity? And this "voice," therefore, is none other than Jesus? John 1:3 has the Word already existing in the beginning. Think of your own word. Does it not emanate from you? Is it somehow less than you? And if you were eternal would not your "voice" or "word"also be eternal? Would it somehow be necessary to create your "voice?" 1 Cor. 1:24 calls Christ the power and wisdom of God. Ask again, was there ever a time that God was powerless or lacking wisdom? Could the power and wisdom of God be less than God? Would they ever have needed to be created?
