Not fulfilled grasshopper.
For example, Christ makes a break in Luke 21 between the armies surrounding Israel and the end of the age. I think it is around verse 25 or 26.
So the destruction of Jerusalem does answer one of the questions.
Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
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. 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.
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.
27 And then shall they see the Son of man coming in a cloud with power and great glory.
28 And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.
I don't see any indication that Jesus has changed subjects.
Mark 13:1 And as he went out of the temple, one of his disciples saith unto him, Master, see what manner of stones and what buildings are here!
2 And Jesus answering said unto him, Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down.
3 And as he sat upon the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately,
4
Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled?
Only one subject in mind.
Mark also puts the Abomination of Desolation at the time of the fall of Jerusalem:
14 But when
ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,)
then let them that be in Judaea flee to the mountains: 15
And let him that is on the housetop not go down into the house, neither enter therein, to take any thing out of his house:
If you notice Luke puts the fleeing to the Mountains BEFORE the supposed transition verse of 25 or 26:
Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
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.
And as you saw Mark put the Abomination of Desolation at that same time.
Luke also in Chapter 17 puts it at the time when the Son of Man is revealed:
Luke 17:24
For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day. 25 But first must he suffer many things, and be rejected of this generation.
26
And as it was in the days of Noe , so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noah entered into the ark, and the flood came, and destroyed them all.
28
Likewise also as it was in the days of Lot ; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
30 Even thus shall
it be in the day when the Son of man is revealed .
31
In that day , he which shall
be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
Many dispies and partial prets say Matt.24 transitions from the fall of Jerusalem to the future coming at verse 35 or 36;
Matt 24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
35 Heaven and earth shall pass away, but my words shall not pass away.
36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
37 But as the days of Noah were, so shall also the coming of the Son of man be.
But again there is no indication of a change of subject. Also he uses the reference to Noah AFTER the supposed transition verse. But Luke uses the reference to Noah at the destruction of Jerusalem.
It seems to me that either the Olivet Discourse is all future or all past. If you carefully study Matt 24, Mark 13, Luke 17, and Luke 21, I think you will see there are major problems in trying to divide it between the events of AD70 and a future event some 2000 years later. This is one of the major reasons I accept the full-preterist veiw as opposed to the partial-preterist view.
In reading the works of both futurist and partial-prets they all seem to acknowledge the difficulty of dividing the Discourse.
