I see Jesus Answering the questions the Disciples asked and that His Answer to their 3rd question about "The End of The World", as they are presented in Matthew 24:3b
Question 1: "Tell us, when shall these things be?"
Question 2: "and what
shall be the sign of thy coming,"
Question 3: "and of the end of the world?"
Since you are in Mark 13, in Mark 13:4, there are 2 questions asked:
1.
4 "Tell us, when shall these things be?"
2. "and what
shall be the sign when all these things shall be fulfilled?"
Taking all three from Matthew gives us the context for Jesus' three Answers.
In Matthew, the third question is about, "The End of The World".
Jesus Answers that question begining at verse 31, in the Mark 13 passage you quoted,
"
31 Heaven and earth shall pass away: but my words shall not pass away.
32."But of that day and
that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
33."Take ye heed, watch and pray: for ye know not when the time is.
34."For the Son of man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch.
35."Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:
36."Lest coming suddenly he find you sleeping.
37. "And what I say unto you I say unto all, Watch."
So, from Mark 13:31 to 37, we are given information, from Jesus, that He is Answering about, when will be "The End of The World" that is included as the third question from Matthew 24:3.
That third question is Answered in Matthew 24: 35 to 51. Everything mentioned in Matthew 24: 35 to 51, is in regard to Jesus Answering about "The End of The World".
(Nothing prior to Matthew 24:35 is in regard to Jesus Answering about "The End of The World", at all. Not one word, but we'll get to all that and show it, or at least refer to the passages, from Mark).
It is interesting, since you are using the Mark passage that prior to Matthew 24:35, Jesus uses the word, 'fulfilled", when He Says, "This generation shall not pass, till all these things be fulfilled", because that section of His Answer is to the Disciples second question, in Mark 13:4, which includes the word "fulfilled": "and what
shall be the sign when all these things shall be fulfilled?"
THE "these things" in that question that would be "fulfilled" are in the Disciples' second question and is Answered, by Jesus, in Mark 13: 14 to 30.
The second question?
That is: "and what
shall be the sign when all these things shall be fulfilled?"
And so, THERE, they are specifically asking about "the sign" when these things would be fulfilled.
What "things" should be 'fulfilled' ?
Those things fulfilled in the first question: Mark 13:
4 "Tell us, when shall these things be?"
With regard to...?
Mark 13: 1, 2: "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."
In Mark 13: 5 to 13 Jesus Answers the Disciples' first question, in Mark 13:
4 "Tell us, when shall these things be?", regarding, The Tempel, after Jesus Had Told them, "Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down."
In Mark 13: 14 to 30.
JESUS Answers their second question,
That is: "and what
shall be the sign when all these things shall be fulfilled?",
which refers to...?
The Tempel, still, after Jesus Had Told them, "Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down."
First the Disciples ask, "when will all the stones of the building Temple be thrown down?"
and there second question is asking for a "sign", of the same thing, "when will we actually see some sign of the exact time when all the stones of the building Temple be thrown down?"
The third question Jesus Answers is not in Mark, but is in Matthew 24:3: "what
shall be the sign of.... the end of the world?"
Mark 13: 31 to 37 covers that third question.
Prior to Mark 13:31, there is no reference to "The End of The World".
What I just said there will seem like the strangest thing possible, but it is the key to the Interpretation.
There is no stressing or staining.
The wording and phrases prior to Mark 13: 31 SEEM to have 'lanuage' that talks about 'nothing else' but "The End of The World",... unless....... we consider... 'lanuage'.... used.... In The Bible.
All those expressions prior to Mark 13: 31 have mostly already been used.
They mean something.
Also: Nothing prior to Matthew 24:35 is in regard to Jesus Answering about "The End of The World", at all. Not one word.
The Bible Means What it Says.
Just like Revelation 20 means something by "one thousand years" and it is NOT AT ALL "one thousand years",.... even though that passage says those words SIX TIMES.
THE WORDS mean What God Means, however.
Try to figure a little of this out by looking at the 3 questions I mentioned and then read where I said Mark answers each one.
You'll go nuts.
But it can be shown that that is the One Interpretation and actually the rest of stuff 'celebs', or whoever makes up really are nuts, for real.
