Here's the text with some surrounding context and an excerpt from Mat 24 {btw, I prefer to post relevant texts on threads rather than having to look them up so everyone can see them, myself included},

Lu 21 (NIV)
20"When you see Jerusalem being surrounded by armies, you will know that its desolation is near. 21Then 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. 22For this is the time of punishment in fulfillment of all that has been written. 23How 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. 24They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampled on 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. 26Men will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27At that time they will see the Son of Man coming in a cloud with power and great glory. 28When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near."
29He told them this parable: "Look at the fig tree and all the trees. 30When they sprout leaves, you can see for yourselves and know that summer is near. 31Even so, when you see these things happening, you know that the kingdom of God is near.
32"I tell you the truth, this generation will certainly not pass away until all these things have happened. 33Heaven and earth will pass away, but my words will never pass away.
And for comparison & contrast:
Matthew 24 (NIV)
15"So when you see standing in the holy place 'the abomination that causes desolation,' spoken of through the prophet Daniel—let the reader understand— 16then let those who are in Judea flee to the mountains. 17Let no one on the roof of his house go down to take anything out of the house. 18Let no one in the field go back to get his cloak. 19How dreadful it will be in those days for pregnant women and nursing mothers! 20Pray that your flight will not take place in winter or on the Sabbath. 21For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. 22If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened. 23At that time if anyone says to you, 'Look, here is the Christ!' or, 'There he is!' do not believe it. 24For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect—if that were possible. 25See, I have told you ahead of time.
26"So if anyone tells you, 'There he is, out in the desert,' do not go out; or, 'Here he is, in the inner rooms,' do not believe it. 27For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. 28Wherever 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.' {Is. 13:10; 34:4, + other OT parallels}
30"At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory. 31And 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. 33Even so, when you see all these things, you know that it {some versions have: or "he"} is near, right at the door. 34I tell you the truth, this generation will certainly not pass away until all these things have happened. 35Heaven and earth will pass away, but my words will never pass away.
