The Book of Revelation tells what will be the last message that the God of heaven sends to this dark world

The Book of Revelation tells what will be the last message that the God of heaven sends to this dark world. It's a three-fold message in Revelation 14 and then amplified further in chapter 18 when the message swells to a loud cry and the entire earth is to be lightened with its glory. Much as we all dislike controversy and tension, this three-fold message will arouse the most intense opposition of any in history, resulting in a polarization of humanity into two opposing groups: those who truly keep the commandments of God and the faith of Jesus, and those who will constitute a "Babylon" in rebellion against God by accepting and enforcing what is called "the mark of the beast."

This crisis will be brought about deliberately by the work of the Holy Spirit, and no one will be able to stop it from happening. And the three-fold message will not be a triumphalist call to legalism but a revelation of what Christ accomplished for humanity by His sacrifice. This is evident by the fact that some 25 times He is portrayed in Revelation as "the Lamb," and the final "harvest" will be a people "who follow the Lamb whithersoever He goeth" (14:4). He is revealed in Revelation as "a Lamb as it had been slain ... from the foundation of the world" (5:6; 13:8).

The call to "worship Him" results in a vast throng who sing from the depths of their hearts, "Worthy is the Lamb that was slain, ... Blessing, and honour, and glory, and power, be unto Him who sits upon the throne, and unto the Lamb for ever" (5:12, 13). No one will ever sing such a song unless his/her heart has been humbled into the dust by a realization of what it cost that Lamb of God to save us, who "has redeemed us to God by [His] blood out of every kindred, and tongue, and people, and nation" (5:9; cf. 14:6, 7).

Clearly, the message that is to lighten the earth with glory will be about Christ and Him crucified, about "His blood." "When I survey the wondrous cross, ... I pour contempt on all my pride." That's the essence of the third angel's message.
