I looked and saw blue, red, and yellow uniforms on the riders. I saw the war and was afraid. Then Jesus came and said, “Look! The victory is Mine.” Only the church in Philadelphia was given the Word that they would be kept from the “hour of trouble” to test mankind, Revelation 3:10. So, if that trouble comes upon you and you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved, Romans 10:9.
from Revelation 9 (NIV):
12 The first woe is past; two other woes are yet to come.
13 The sixth angel sounded his trumpet, and I heard a voice coming from the four horns of the golden altar that is before God. 14 It said to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.” 15 And the four angels who had been kept ready for this very hour and day and month and year were released to kill a third of mankind. 16 The number of the mounted troops was twice ten thousand times ten thousand. I heard their number.
17 The horses and riders I saw in my vision looked like this: Their breastplates were fiery red, dark blue, and yellow as sulfur. The heads of the horses resembled the heads of lions, and out of their mouths came fire, smoke and sulfur. 18 A third of mankind was killed by the three plagues of fire, smoke and sulfur that came out of their mouths. 19 The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury.
20 The rest of mankind who were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk. 21 Nor did they repent of their murders, their magic arts, their sexual immorality or their thefts.
from Revelation 11:
15 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.”
16 And the twenty-four elders, who were seated on their thrones before God, fell on their faces and worshiped God, 17 saying:
“We give thanks to you, Lord God Almighty,
the One who is and who was,
because you have taken your great power
and have begun to reign.
18 The nations were angry,
and your wrath has come.
The time has come for judging the dead,
and for rewarding your servants the prophets
and your people who revere your name,
both great and small—
and for destroying those who destroy the earth.”
19 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.
