Revelation 14:7

Saying... — These words declare what ought to be the effect of the gospel. Those to whom it is preached are sitting inactive on the earth. They must be roused to fear God and give Him glory. They must not fear the powers of evil, the wild beasts, &c., or be afraid of their terror (1 Peter 3:14). They must realise that there is an hour of judgment at hand, which will discriminate between the worshippers of the world and of God. Let them learn to worship the Creator of all, and to turn from the worship of lesser and lower.

If we ask when this gospel angel appeared, our answer must be that the whole cycle of the gospel preaching is included in the vision, though doubtless there have been ages when the light of the glad tidings of God has gone forth with revived lustre, and when the warnings against easy acquiescence in evil have been given with unmistakable distinctness.
