The testimony of Jesus is the spirit, the central subject, of Revelation. Throughout Revelation Jesus Christ is carrying out God’s economy to eliminate God’s enemies and to develop His corporate testimony, which consummates with New Jerusalem. Now we come to chapters 18-19.
Revelation 18:1 says, “I saw another Angel coming down out of heaven, having great authority; and the earth was illumined with His glory.” This Angel is Jesus Christ. He is the One with great authority. He is also the One who fills the earth with glory, by Himself here and later through New Jerusalem.
After the judgement in chapter 18, chapter 19 begins with praise, “a loud voice of a great multitude in heaven, saying, Hallelujah! The salvation and the glory and the power are of our God.”
In 19:5 is the exhortation, “Praise our God, all His slaves and those who fear Him, the small and the great.” We are His slaves both in this time and in New Jerusalem (Rev. 22:3). A primary duty is to praise Him. In 19:6 the response to the exhortation is “the voice of a great multitude and like the sound of many waters and like the sound of mighty thunders, saying, Hallelujah! For the Lord our God the Almighty reigns.”
This voice of the multitude marks the start of the next age with the visible kingdom of God on earth, brought in by the prior judgements and by the visible second coming of Jesus Christ. This is the first stage of the visible kingdom; New Jerusalem is the ultimate stage.
