years

What has been covered so far:

Satan was cast down to earth and released the demons: (stars falling from the sky)

The horsemen of the apocalypse are released, resulting in a devastating world war. (the horsemen of the apocalypse)

Now the last three and a half years begin.

During these three and a half years, the persecution of Christians will be particularly severe, as represented by the fact that the temple courtyard will be trampled on for forty-two months, as we can read in Revelation chapter eleven.

Rev. 11:2 but do not measure the court outside the temple; leave that out, for it is given over to the nations, and they will trample the holy city for forty-two months.

Rev. 13:11 Then I saw another beast rising out of the earth. It had two horns like a lamb and it spoke like a dragon.
12 It exercises all the authority of the first beast in its presence, and makes the earth and its inhabitants worship the first beast, whose mortal wound was healed. 13 It performs great signs, even making fire come down from heaven to earth in front of people, 14 and by the signs that it is allowed to work in the presence of the beast it deceives those who dwell on earth, telling them to make an image for the beast that was wounded by the sword and yet lived. 15 And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not worship the image of the beast to be slain. 16 Also it causes all, both small and great, both rich and poor, both free and slave,[5] to be marked on the right hand or the forehead, 17 so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. 18 This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.

The beast from Revelation thirteen, that is, the union of states as a world government, will blaspheme against the Holy One for forty-two months.

Rev.13:5 And the beast was given a mouth uttering haughty and blasphemous words, and it was allowed to exercise authority for forty-two months. 6 It opened its mouth to utter blasphemies against God, blaspheming his name and his dwelling, that is, those who dwell in heaven.

A second beast, which looks like a sheep but has the mouth of a dragon, will now make an image of the beast and force all people to worship this beast. Or to kill those who do not worship the image of the beast.
We read Revelation chapter 13 verses 11 to 18.

However, Jesus gives authority to his church, represented by the two witnesses. We read this in Revelation chapter 11, verses 3 to 6.
3 And I will grant authority to my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth.” 4 These are the two olive trees and the two lampstands that stand before the Lord of the earth. 5 And if anyone would harm them, fire pours from their mouth and consumes their foes. If anyone would harm them, this is how he is doomed to be killed. 6 They have the power to shut the sky, that no rain may fall during the days of their prophesying, and they have power over the waters to turn them into blood and to strike the earth with every kind of plague, as often as they desire.

The task of the witnesses will be to warn people not to worship the image of the beast!
This is represented by the warning of the angels in chapter 14.

Rev.14:9 And another angel, a third, followed them, saying with a loud voice, “If anyone worships the beast and its image and receives a mark on his forehead or on his hand,10 he also will drink the wine of God’s wrath, poured full strength into the cup of his anger, and he will be tormented with fire and sulfur in the presence of the holy angels and in the presence of the Lamb.11 And the smoke of their torment goes up forever and ever, and they have no rest, day or night, these worshipers of the beast and its image, and whoever receives the mark of its name.”12 Here is a call for the endurance of the saints, those who keep the commandments of God and their faith in Jesus. 13 And I heard a voice from heaven saying, “Write this: Blessed are the dead who die in the Lord from now on.” “Blessed indeed,” says the Spirit, “that they may rest from their labors, for their deeds follow them!”

Rev.11,11 But after the three and a half days a breath of life from God entered them, and they stood up on their feet, and great fear fell on those who saw them. 12 Then they heard a loud voice from heaven saying to them, “Come up here!” And they went up to heaven in a cloud, and their enemies watched them.

The end times last42 months (Rev. 13:5; 11:2) 1260 days (Rev. 11:3, 12:6)
3 1/2 years (Rev. 12:14)It is the time of the final decision!

Rev.11:7 And when they have finished their testimony, the beast that rises from the bottomless pit will make war on them and conquer them and kill them, 8 and their dead bodies will lie in the street of the great city that symbolically is called Sodom and Egypt, where their Lord was crucified. 9 For three and a half days some from the peoples and tribes and languages and nations will gaze at their dead bodies and refuse to let them be placed in a tomb,
