He told them a parable. "See the fig tree, and all the trees. When they are already budding, you see it and know by your own selves that the summer is already near. Even so you also, when you see these things happening, know that the Kingdom of God is near. Most certainly I tell you, this generation will not pass away until all things are accomplished. Heaven and earth will pass away, but my words will by no means pass away."
— Luke 21:29-33
Below are the signs that Jesus speaks of in this parable:
The Destruction of the Temple and Signs of the End Times
5 Some of his disciples were remarking about how the temple was adorned with beautiful stones and with gifts dedicated to God. But Jesus said, 6 “As for what you see here, the time will come when not one stone will be left on another; every one of them will be thrown down.”
7 “Teacher,” they asked, “when will these things happen? And what will be the sign that they are about to take place?”
8 He replied: “Watch out that you are not deceived. For many will come in my name, claiming, ‘I am he,’ and, ‘The time is near.’ Do not follow them. 9 When you hear of wars and uprisings, do not be frightened. These things must happen first, but the end will not come right away.”
10 Then he said to them: “Nation will rise against nation, and kingdom against kingdom. 11 There will be great earthquakes, famines and pestilences in various places, and fearful events and great signs from heaven.
12 “But before all this, they will seize you and persecute you. They will hand you over to synagogues and put you in prison, and you will be brought before kings and governors, and all on account of my name.13 And so you will bear testimony to me. 14 But make up your mind not to worry beforehand how you will defend yourselves. 15 For I will give youwords and wisdom that none of your adversaries will be able to resist or contradict. 16 You will be betrayed even by parents, brothers and sisters, relatives and friends, and they will put some of you to death. 17 Everyone will hate you because of me. 18 But not a hair of your head will perish.19 Stand firm, and you will win life.
20 “When you see Jerusalem being surrounded by armies, you will know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those in the city get out, and let those in the country not enter the city. 22 For this is the time of punishment in fulfillment of all that has been written. 23 How dreadful it will be in those days for pregnant women and nursing mothers! There will be great distress in the land and wrath against this people. 24 They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampledon by the Gentiles until the times of the Gentiles are fulfilled.
25 “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.26 People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27 At that time they will see the Son of Man coming in a cloud with power and great glory.28 When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.” - Luke 21:5-28
