Daniel 12:4 But you, Daniel, roll up and seal the words of the scroll until the time of the end. Many will go here and there to increase knowledge.

Luke 21:25-26 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. Men will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken.

I Thessalonians 5:2-3 For you know very well that the day of the Lord will come like a thief in the night. While people are saying, 'Peace and safety,' destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.

II Timothy 3:1-5 But mark this: There will be terrible times in the last days. 2 People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, 3 without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, 4 treacherous, rash, conceited, lovers of pleasure rather than lovers of God.

II Peter 3:3-4 3 Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. 4 They will say, “Where is this ‘coming’ he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.” 5 But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water. 6 By these waters also the world of that time was deluged and destroyed. 7 By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly.

Matthew 24:42-44 So be prepared, for you don't know what day your Lord is coming. Just as a man can prevent trouble from thieves by keeping watch for them, so you can avoid trouble by always being ready for My unannounced return.

Matthew 24:3-32 3 As Jesus was sitting on the Mount of Olives, the disciples came to him privately. “Tell us,” they said, “when will this happen, and what will be the sign of your coming and of the end of the age?” 4 Jesus answered: “Watch out that no one deceives you. 5 For many will come in my name, claiming, ‘I am the Messiah,’ and will deceive many. 6 You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. 7 Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. 8 All these are the beginning of birth pains. 9 “Then you will be handed over to be persecuted and put to death, and you will be hated by all nations because of me. 10 At that time many will turn away from the faith and will betray and hate each other, 11 and many false prophets will appear and deceive many people. 12 Because of the increase of wickedness, the love of most will grow cold, 13 but the one who stands firm to the end will be saved. 14 And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come. 15 “So when you see standing in the holy place ‘the abomination that causes desolation,’[a] spoken of through the prophet Daniel—let the reader understand— 16 then let those who are in Judea flee to the mountains. 17 Let no one on the housetop go down to take anything out of the house. 18 Let no one in the field go back to get their cloak. 19 How dreadful it will be in those days for pregnant women and nursing mothers! 20 Pray that your flight will not take place in winter or on the Sabbath. 21 For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. 22 “If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened. 23 At that time if anyone says to you, ‘Look, here is the Messiah!’ or, ‘There he is!’ do not believe it. 24 For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect. 25 See, I have told you ahead of time. 26 “So if anyone tells you, ‘There he is, out in the wilderness,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. 27 For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. 28 Wherever there is a carcass, there the vultures will gather. 29 “Immediately after the distress of those days “‘the sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken.’[b] 30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth[c] will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory.[d] 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other. 32 “Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. 33 Even so, when you see all these things, you know that it[e] is near, right at the door. 34 Truly I tell you, this generation will certainly not pass away until all these things have happened. 35 Heaven and earth will pass away, but my words will never pass away.
