The survivors were terrified and gave glory to the God of heaven

 Revelation 11:1-19

They have power to shut up the heavens so that it will not rain during the time they are prophesying; and they have power to turn the waters into blood and to strike the earth with every kind of plague as often as they want.

Now when they have finished their testimony, the beast that comes up from the Abyss will attack them, and overpower and kill them. Their bodies will lie in the public square of the great city—which is figuratively called Sodom and Egypt—where also their Lord was crucified.

For three and a half days some from every people, tribe, language and nation will gaze on their bodies and refuse them burial. 

But after the three and a half days the breath of life from God entered them, and they stood on their feet, and terror struck those who saw them. Then they heard a loud voice from heaven saying to them, “Come up here.” And they went up to heaven in a cloud, while their enemies looked on.

At that very hour, there was a severe earthquake and a tenth of the city collapsed. Seven thousand people were killed in the earthquake, and the survivors were terrified and gave glory to the God of heaven.

The seventh angel sounded his trumpet, and there were loud voices in heaven, which said: “The kingdom of the world has become the kingdom of our Lord and of his Messiah, and he will reign for ever and ever.”

Then God’s temple in heaven was opened, and within his temple was seen the ark of his covenant. And there came flashes of lightning, rumblings, peals of thunder, an earthquake and a severe hailstorm.

Why?

This is the end of the world, and it is the time of the Lord. Welcome his people to come up to heaven, and all the images described in the Old Testament could be seen this time.

It is hard to imagine this feature for us. John described detailed information, encouraging us to have faith, walk in the way of faith, live, and hope.

How?

Because I believe Jesus is the Son of the Lord, so believe all that the Bible mentions about the Lord, Jesus Christ, and the Bible. My mission is to preach the gospel to more people.
