The great tribulation is seen here
Matthew 24:1–22 (NASB 2020) — 1 Jesus left the temple area and was going on His way when His disciples came up to point out the temple buildings to Him. 2 But He responded and said to them, “Do you not see all these things? Truly I say to you, not one stone here will be left upon another, which will not be torn down.” 3 And as He was sitting on the Mount of Olives, the disciples came to Him privately, saying, “Tell us, when will these things happen, and what will be the sign of Your coming, and of the end of the age?” 4 And Jesus answered and said to them, “See to it that no one misleads you. 5 For many will come in My name, saying, ‘I am the Christ,’ and they will mislead many people. 6 And you will be hearing of wars and rumors of wars. See that you are not alarmed, for those things must take place, but that is not yet the end. 7 For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places. 8 But all these things are merely the beginning of birth pains. 9 “Then they will hand you over to tribulation and kill you, and you will be hated by all nations because of My name. 10 And at that time many will fall away, and they will betray one another and hate one another. 11 And many false prophets will rise up and mislead many people. 12 And because lawlessness is increased, most people’s love will become cold. 13 But the one who endures to the end is the one who will be saved. 14 This gospel of the kingdom shall be preached in the whole world as a testimony to all the nations, and then the end will come. 15 “Therefore when you see the ABOMINATION OF DESOLATION which was spoken of through Daniel the prophet, standing in the holy place—let the reader understand—16 then those who are in Judea must flee to the mountains. 17 Whoever is on the housetop must not go down to get things out of his house. 18 And whoever is in the field must not turn back to get his cloak. 19 But woe to those women who are pregnant, and to those who are nursing babies in those days! 20 Moreover, pray that when you flee, it will not be in the winter, or on a Sabbath. 21 For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will again. 22 And if those days had not been cut short, no life would have been saved; but for the sake of the elect those days will be cut short.
It concerns Jerusalem and the temple and took place in 70 A.D.
There was no rapture. Historically Jewish Christian were told to escape to Pella and did
The beginning of a parable which is a prophecy.
Lk 21:29 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.
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.
33 Heaven and earth shall pass away: but my words shall not pass away.
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.
The end of the parable.
The suggested response to the prophecy.
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.
Do you believe this prophecy strong enough to do as Jesus said, pray that you will be worthy enough to escape the things he has cataloged? In verse 34 he speaks of "that day" which almost always means the "day of the Lord" that occupies so much of the warnings of the prophets.
Let me say first of all that your NASB does great damage to the typology of the temple doctrine in the scriptures by changing the actions of Jesus, who is God, from leaving the temple to leaving the grounds. It is my belief that some men will promote ignorance by such actions and oppose the truths of God and persuade others to oppose him as well.
For Jesus to not come back to the temple after rebuking the national leaders was highly significant.
Here is a truth you may not know. There are 89 chapters in the 4 gospel accounts of the earthly ministry of Jesus Christ in Israel. There are 28 chapters in Matthew, 16 chapters in Mark, 24 chapters in Luke and 21 chapters in John. 28 + 16 + 24 + 21 = 89 chapters total. Now the public ministry of Jesus Chris
t was 3 1/2 years but we have almost exactly 1/3 of the chapters devoted to the last seven days of his ministry to Israel and to a couple of events immediately after his resurrection from the dead on the day after the sabbath, or day 8. The number 8 is the number God uses in his scriptures of truth for new things. Things like a new covenant. a new creation in Christ, a new birth, a new man, etc, The number 9 is associated with fruit bearing and it is interesting what Jesus said about fruit bearing and to whom he said it. It was in John 12, the last chapter in John before he arrived in Jerusalem to die and rise again from the dead. Take a look;
Joh 12:20 And there were certai
n Greeks among them that came up to worship at the feast:
21 The same came therefore to Philip, which was of Bethsaida of Galilee, and desired him, saying, Sir, we would see Jesus.
22 Philip cometh and telleth Andrew: and again Andrew and Philip tell Jesus.
23 And Jesus answered them, saying, The hour is come, that the Son of man should be glorified.
24 Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.
25 He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal.
26 If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour.
This is an amazing response to these men, these gentiles. His death and being planted in the ground would mean life for these Greeks and the world but until then he could not bear any fruit among them. Therefore he did not respond to them at that time.
But back to the 89 chapters.
In Matthew, he came to Jerusalem in chapter 21 + 8 = 28
In Mark, in chapter 11 + 6 = 16
Luke, in chapter 19:28 = 6 = 24
John, in chapter 13 +9 = 21
8 +6 + 6 +9 = 29 chapters
29 / 89 = 32.5842%
All of these chapters above were written after the Jewish rulers had decided to kill Jesus Christ.
47 Then gathered the chief priests and the Pharisees a council, and said, What do we? for this man doeth many miracles.
48 If we let him thus alone, all men will believe on him: and the Romans shall come and take away both our place and nation.
49 And one of them, named Caiaphas, being the high priest that same year, said unto them, Ye know nothing at all,
50 Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not.
51 And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;
52 And not for that nation only, but that also he should gather together in one the children of God that were scattered abroad.
53 Then from that day forth they took counsel together for to put him to death.
So Jesus Christ came to Jerusalem knowing that he would be put to death by his own countrymen, those he came to save. He was fulfilling his office as the perfect prophet and most of his parables that he spoke as he met with Israel in the temple from the first day of the week until the fifth day before he left for the final time was about a finality. His parables were about the end of the day, about supper time, about harvest time, about the refusal of those who had been previously bidden to the marriage refusing to come and a delay while the master sent out his servants to invite those in the hedges and highways so his house will be full and the marriage feast be filled with guests. We have the full prophecy of this present age in these parables of Jesus Christ and he has not spoken another word while he awaits the time of the feast.
Ro 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
There is a reckoning for both Jews and gentiles who would not respond to his invitation to come to his supper. It is death to all before his supper.
Lu 14:16 Then said he unto him, A certain man made a great supper, and bade many:
17 And sent his servant at supper time to say to them that were bidden, Come; for all things are now ready.
18 And they all with one consent began to make excuse. The first said unto him, I have bought a piece of ground, and I must needs go and see it: I pray thee have me excused.
19 And another said, I have bought five yoke of oxen, and I go to prove them: I pray thee have me excused.
20 And another said, I have married a wife, and therefore I cannot come.
21 So that servant came, and shewed his lord these things. Then the master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in hither the poor, and the maimed, and the halt, and the blind.
22 And the servant said, Lord, it is done as thou hast commanded, and yet there is room.
23 And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled.
24 For I say unto you, That none of those men which were bidden shall taste of my supper.
What is going to happen to them?
Lu 19:11 And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that the kingdom of God should immediately appear.
12 He said therefore, A certain nobleman went into a far country to receive for himself a kingdom, and to return.
13 And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come.
14 But his citizens hated him, and sent a message after him, saying, We will not have this [man] to reign over us.
.......
26 For I say unto you, That unto every one which hath shall be given; and from him that hath not, even that he hath shall be taken away from him.
27 But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me.
Zec 14:9 And the LORD shall be king over all the earth: in that day (the day of the Lord) shall there be one LORD, and his name one.
For one third of the ministry of Jesus Christ to be devoted to the last 8 days of his life should instruct us about how important they are. The remainder of the history in time is laid out in the parables of Jesus. A good deal if not most of his prophecies are in these chapters.
If one is interesting in the chronology of these days, they can be tracked day by day in the gospel of Mark.
