And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:
For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.
But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.
And then shall they see the Son of man coming in the clouds with great power and glory.
Verily I say unto you, that this generation shall not pass, till all these things be done.
Heaven and earth shall pass away: but my words shall not pass away.
But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father. Mark 13:4-8&10&19&21&22&24-26&30-32
Watch ye therefore: for ye know not when the master of the house cometh ... Lest coming suddenly he find you sleeping. Mark 13:35
And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them.
But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end is not by and by.
Then said he unto them, Nation shall rise against nation, and kingdom against kingdom:
And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven. Luke 21:8-11
There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. Luke 21:25
For the Lord himself will come down from Heaven, with a loud command, with the voice of the Archangel and with the trumpet call of God, and the dead in Christ will rise first.
We who are still alive will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. I Thessalonians 4:16&17
There will be terrible times in the last days ... Evil men and impostors go from bad to worse deceiving and being deceived. I Timothy 3:1&13
This know also, that in the last days perilous times shall come.
For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
Traitors, heady, highminded, lovers of pleasures more than lovers of God;
Having a form of godliness, but denying the power thereof: from such turn away.
For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
Ever learning, and never able to come to the knowledge of the truth. II Timothy 3:1-7
And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. Revelation 6:13&14
And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
And I saw the seven angels which stood before God; and to them were given seven trumpets.
And the angel took the censer, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
And the seven angels which had the seven trumpets prepared themselves to sound.
The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up.
And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea
And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.
And the third angel sounded, and there fell a great star from, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters;
And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.
And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise.
And I beheld, and heard an angel flying through the midst of heaven, saying with a loud voice, Woe, woe, woe, to the inhabiters of the earth by reason of the other voices of the trumpet of the three angels, which are yet to sound! became blood. Revelation 8:1&2&5-13
And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.
And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.
And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men. Revelation 9:1-7
And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men.
And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them. Revelation 9:15&16
And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified. Revelation 11:7&8
And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven. Revelation 11:13
And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion: and the dragon gave him his power, and his seat, and great authority.
And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast.
And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon.
And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six. Revelation 13:1-4&7&11&12 &18
