You are holding fast, and have borne up for my name's sake, and have not grown weary.

So remember the heights from which you have fallen, and repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will] and do the works you did at first [when you first knew Me]; otherwise, I will visit you and remove your lampstand (the church, its impact) from its place—unless you repent.

I know thy works, and where thou dwellest, even where Satan's seat is: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas was my faithful martyr, who was slain among you, where Satan dwelleth.

But I have a few [things] against you: that you have there those who hold fast to the teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel, to eat food sacrificed to idols and to commit sexual immorality.

Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.

Because you have kept the word of My endurance [My command to persevere], I will keep you [safe] from the hour of trial, that hour which is about to come on the whole [inhabited] world, to test those who live on the earth.

Behold, I come quickly: hold that fast which thou hast, that no man take thy crown.

After these things I looked, and this is what I saw: a vast multitude which no one could count, [gathered] from every nation and from all the tribes and peoples and languages [of the earth], standing before the throne and before the Lamb (Christ), dressed in white robes, with palm branches in their hands;

And the second angel sounded, and there was cast into the sea as it were a vast mountain burning with fire: and the third part of the sea became blood;

The name of the star is 'Wormwood;' and a third part of the waters were turned into wormwood, and vast numbers of the people died from drinking the water, because it had become bitter.

and he opened the depths of the bottomless pit. And smoke came up out of the pit resembling the smoke of a vast furnace, so that the sun was darkened, and the air also, by reason of the smoke of the pit.

They had breastplates (scales) like breastplates made of iron; and the [whirring] noise of their wings was like the [thunderous] noise of countless horse-drawn chariots charging [at full speed] into battle.

This made the Dragon furiously angry with the woman, and he went elsewhere to make war upon her other children--those who keep God's commandments and hold fast to the testimony of Jesus.

After this I heard something like the loud voice of a vast multitude in heaven, saying:

Hallelujah!
Salvation, glory, and power belong to our God,

Then I heard something like the shout of a vast multitude, and like the boom of many pounding waves, and like the roar of mighty peals of thunder, saying,
