Jesus, in Mathew 24 & 25 is answering a question, that was asked by His disciples.So He has the responsibility to answer them in such a way that they learn the answer, not only them but us as well, to whom the answer pertains, or as Paul said, to whom "the ends of the ages have come upon"[1 Cor 10:11].
Jesus concludes His "overall view", that gives a general description of events that lead up to the end, in verse's 13,14.
13 But he who endures to the end shall be saved. 14 And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.
Now, in verse 15, The Lord is "switching gears" by giving a more specific account of the end.By using the word "Therefore", He is defining what He is about to say from what He has just said.
"When you see" defines the group of people that will experience what He is now saying. This description flows from when He first says "when you see" to the end of His explanation, which ends with "when you see", and defines that to "this generation". The generation that see's these things, will see The Lord Come.
15 "Therefore when you see the 'abomination of desolation,' spoken of by Daniel the prophet, standing in the holy place" (whoever reads, let him understand), 16 then let those who are in Judea flee to the mountains. 17 Let him who is on the housetop not go down to take anything out of his house. 18 And let him who is in the field not go back to get his clothes. 19 But woe to those who are pregnant and to those who are nursing babies in those days! 20 And pray that your flight may not be in winter or on the Sabbath. 21 For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be. 22 And unless those days were shortened, no flesh would be saved; but for the elect's sake those days will be shortened. 23 Then if anyone says to you, 'Look, here is the Christ!' or 'There!' do not believe it. 24 For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect. 25 See, I have told you beforehand. 26 Therefore if they say to you, 'Look, He is in the desert!' do not go out; or 'Look, He is in the inner rooms!' do not believe it. 27 For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be. 28 For wherever the carcass is, there the eagles will be gathered together. 29 "Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. 30 Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And He will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other. 32 "Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near. 33 So you also, when you see all these things, know that it is near--at the doors! 34 Assuredly, I say to you, this generation will by no means pass away till all these things take place.
The generation that see's the fig tree bloom again will see the detailed events of the Lord's return!
