Luke 21:1 And he looked up, and saw the rich men casting their gifts into the treasury.
2 And he saw also a certain poor widow casting in thither two mites.
3 And he said, Of a truth I say unto you, that this poor widow hath cast in more than they all:
4 For all these have of their abundance cast in unto the offerings of God: but she of her penury hath cast in all the living that she had.
The most important verses in this chapter.
5 And as some spake of the temple, how it was adorned with goodly stones and gifts, he said,
6 As for these things which ye behold, the days will come, in the which there shall not be left one stone upon another, that shall not be thrown down.
7 And they asked him, saying, Master, but when shall these things be? and what sign will there be when these things shall come to pass?
8 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.
9 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.
10 Then said he unto them, Nation shall rise against nation, and kingdom against kingdom:
11 And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.
12 But before all these, they shall lay their hands on you, and persecute you, delivering you up to the synagogues, and into prisons, being brought before kings and rulers for my name's sake.
This refers to the apostles, and therefore the previous verses refer to things that will happen after the apostles are delivered up.
13 And it shall turn to you for a testimony.
14 Settle it therefore in your hearts, not to meditate before what ye shall answer:
15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.
This applies to the apostles, but also to all who are in the same situation.
16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death.
17 And ye shall be hated of all men for my name's sake.
18 But there shall not an hair of your head perish.
19 In your patience possess ye your souls.
Therefore these verses also apply to all who are persecuted in the church age.
20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
So then this verse applies to both. In 70AD this took place with the apostles and at the end of the age this will take place again during the Great tribulation.
21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.
22 For these be the days of vengeance, that all things which are written may be fulfilled.
Vengeance for what? For rejecting Jesus. Yes, that applies to 70AD, but it also applies to the end of the age.
23 But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people.
24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Cannot get any clearer than that. The church age is called by Daniel "the times of the Gentiles". Times is plural, hence 2, not 1. In this case 2 thousand years. Jersulem was trodden down of the Gentiles until 1967 when Israel regained control, and yet it was 50 years later when the US recognized Jerusalem as the capital of Israel. One thing is very clear, the times of the Gentiles (nations) is coming to an end.
25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
This is future tense and takes place when the times of the Gentiles ends.
27 And then shall they see the Son of man coming in a cloud with power and great glory.
Once again, future tense, not talking directly to the apostles but to some "they" in the future. He does not say "and then you shall see".
28 And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.
These things began to take place in 1948 when the UN voted for Israel to return, and in 1950 when they had their first Knesset, and in 1967 when they got control of Jerusalem, and in 2017 when Trump recognized Jerusalem, and when the Abraham accords were made, and when they pushed the whole Climate change agenda, perplexity of the sea, and when we saw the Psalm 83 confederacy against Israel, etc.
29 And he spake to them a parable; Behold the fig tree, and all the trees;
30 When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
"All the Trees"? Israel was not the only nation that was formed by the UN, they drew up borders and formed many Middle Eastern nations, all with national trees, at this time.
31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
32 Verily I say unto you, This generation shall not pass away, till all be fulfilled.
There are multiple theories as to what "This generation" refers to and I feel several of them have legitimacy. First, we can look at the generation that rejected Jesus, that has not passed away among the Jews, they still reject Jesus. Second, we can tie the fig tree to the fall of man in Genesis and say this refers to the sinful generation and that also has not passed away. We can also refer to Psalm 90:10 and say that a generation is 70 - 80 years. If we look at 1950 as the beginning of the nation of Israel that would be 2020-2030. (There are two ways to time Israel, one is when the Jews began to return to the land, that is the starting point for the jubilee. They returned in 1923 when the Palestinian mandate went into effect, so 1973 and 2023 would be Jubilee years. In both we have wars over Yom Kippur. The second way is when they "shoot forth the tender leaves" -- works, of a nation, hence the Knesset forms).
33 Heaven and earth shall pass away: but my words shall not pass away.
Once again this word is not to the apostles only but to all of us in every generation.
34 And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares.
35 For as a snare shall it come on all them that dwell on the face of the whole earth.
36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
37 And in the day time he was teaching in the temple; and at night he went out, and abode in the mount that is called the mount of Olives.
38 And all the people came early in the morning to him in the temple, for to hear him.
