4/8/10 Another angel, representing God’s people, goes throughout the earth evangelizing the world with the gospel. The same words here “every nation, tribe, tongue and people” are parallel to Rev 13:7 where the beast wars against the same. Evangelism is war. We demolish strongholds, arguments, anything that sets itself up against the knowledge of God (2 Cor 10:4-5).
So God’s people before the parousia go out proclaiming the gospel. Their message is “fear God.” How do we fear God? Ec 12:13-14 says “Fear God and keep his commandments for this is the whole of man.” We fear God by taking him seriously, by obedience to him. This is what the saints are known for: keeping the commandments (obedience) and having the testimony of Jesus (sharing the gospel, evangelism).
“Give him glory,” is the second part of the gospel message. We teach people holistically how to glorify God in our bodies, in our actions, in our characters, in our obedience. Glorifying God is an all-life encompassing proposition.
This passage has a strong allusion to Ps 96 in which the world is called to fear, glorify, and worship God in a context of judgment–and to do so in the understanding that he is the Creator.
