The Gospel…proclaimed by the 144,000

The Gospel, the good news of the coming Kingdom of Jesus, will be proclaimed to all the world by the 144,000 missionaries selected out of all the Christian people, by Jesus as He stands on Mt Zion. Revelation 14:1-7 THEY will do it, not the angel; used as a metaphor for them.
Proved by Isaiah 66:18b-21 I am coming to gather peoples of every language, they will come to see My glory. I shall put a sign on [some of] them and they will go out to the nations, to the distant shores who have not yet heard of Me or seen My glory. They will declare My glory among all the nations.
My people will gather
[in the holy Land, seen by John in Revelation 7:9-14]….and some of them, I shall take for priests and Levites, says the Lord. Revelation 5:9-10

Note: that Jesus is revealed to His people only, soon after His Day of wrath. As clearly stated in 2 Thessalonians 1:6-10 and the sequence of Revelation 6:12-17, followed by Revelation 7:1-14. Rev 7: 15-17 refers to Eternity, after the Millennium. Paralleled by Revelation 21:4 He will wipe away every tear...…

Then comes Revelation 8:1, which is a time gap of ‘about 20 years’ earth time, when all the rest of the prophesied things will happen, leading up to the glorious Return of Jesus for His Millennium reign.
