"6 Then I saw another angel flying directly overhead, with an eternal gospel to proclaim to those who dwell on earth, to every nation and tribe and language and people. 7 And he said with a loud voice, “Fear God and give him glory, because the hour of his judgement has come, and worship him who made heaven and earth, the sea and the springs of water.”"
Revelation 14:6-13
The vision of the gathered elect of God, preserved and protected from all ultimate harm and brought through it to His eternal glory, is one well calculated to bring encouragement and reassurance to beleaguered saints in any age, whatever the persecutions and perils they might face, and we must think of it in relation to the fearful prophecies of chapter 13. This is just as true of the vision that follows, in which John sees another angel flying 'in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth'. Here our attention is turned once more to the earth, but we see it from the divine standpoint. And now, over against the fearful manifestation of the blasphemous trinity of evil, we see the activity of the Holy Trinity represented by the angel proclaiming the everlasting gospel. We must reject any suggestion that this is a different gospel from the gospel of grace. There is, and can be, but one gospel, and it is no argument to say that here the emphasis is different (7) from that made, for example, in the Acts and the Epistles. There are in fact different notes in the gospel - this we shall turn to later - and elements of fear and warning are just as authentic as those of grace and joy, as we see from Paul's preaching. This vision has in fact a close connection with the preceding verses. It is the presence and preaching of the gospel that is the decisive factor in the bringing about of vv1-5, and it is this that stands over against the 'sealing' of men by the beast (13:16, 17), indicating that even when Satan is doing his worst, the work of God goes on uninterruptedly to its appointed end.
