We can use all three, but there is no use, using one or the other is always the best way, so doing all three hen taking notes off all three is a better way to go else you win up conflating things, from my experience. I will use Matt 24
You get verse 13 correct, that is indeed referring to the end of men's/disciples lives, or running the full marathon.
Now, here is 2 or 3 reasons why I think you get off on the wrong foot. 1.) THE END is not fully comprehended by you. 2.) You don't quite grasp how clever Jesus is with his THREE MENTIONS of false christs/false prophets and understand that Jesus, in ALL THREE are pointing to THREE SPECIFIC TIME PERIODS. 3.) Zechariah shows Israel REPENTING via 1/3 of the Nation coming unto Jesus, in reality, you know that did not happen in AD 70. (It's one of those, YEA, but I got to make it fit moments for you......SMILE, I used to be the same way)
OK, let's discuss why THE END is so important and what it means here. Jesus is speaking about the coming 70th WEEK END where Israel goes through so many troubles that they turn unto Jesus Christ during this 70th week and repent, just like Zechariah 13:8-9 says AND just like Malachi 4:5-6 says.
So, Jesus starts off answering their question about WHEN WLL THESE THINGS BE? (Temples Destruction) And that comes in verses 4-6, he tells them not to let anyone DECEIVE THEM, there will be many that come saying I am Christ or the Messiah who will deceive many, don't believe it, you will hear wars and rumors of wars (from afar in 70 AD) but don't be troubled, the..........END IS NOT YET (70 AD is not the END, that is by and by or LATER ON)
So, Jesus did not want the disciples rushing back unto Jerusalem thinking THE END (70th-week redemption and Jerusalem/Israel being redeemed by Jesus and Jesus reigning there for 1000 years) had come, thus he, LATER ON, tells them SPECIFICALLY what brings THE END where they can not get it wrong, in verse 14. But here Jesus tells them that fake christs will deceive many. John 5:43 is fulfilled here, not during the END TIMES. The Pharisees and Jewish leaders knew Rome was the Fourth Beast, thus they put forth Messianic figures from 66 AD - 70 AD hoping that one would be that hoped-for "Political Savior" they saw the Messiah as. Thus Jesus not only warns them not to come back unto Jerusalem at this time, even though they would hear of wars and rumors of wars and fake christs, he later on in verse 14 explains unto them that the Gospel must be preached unto ALL THE WORLD, and only then would THE END come (70th week). Thus his Disciples could not be TRICKED by Satan, because they knew India and China had to have heard the Gospel before THE END (70th week) could come. Thus Jesus here is telling his disciples what their future would bring AND what brings the 70th-week end times.)
That is why I say verses 4-6 are SPECIFICALLY about 70 AD.
In verses 7-14 we are shown the Church Age, and Jesus was explaining this unto his Disciples, thus the mention of false prophets in verse 11 is specifically about false teachers, notice it's not false christs here as in verse 5, it is false prophets. So, Jesus starts laying down all the signs that lead up to the Second Coming in Matt. 24 29-:31 since this is about the Jews' END TIME fate. But he's also speaking of the Church Age period because Jews are also in the Church, of course, the Disciples were all Jews.
So, Nations will war against Nations, Ethos against Ethos (race against race), there will be earthquakes, famines, and plagues (think of the Black Plague, think of COVID 19 etc.) and Jesus said this is the beginning of Sorrows or a Birthpang, in other words,
Jesus painted the Churh Age as BIRTHING the 70th-week end that was yet to come. He then tried to ready the Disciples for their coming fate (Death) and he says hey, you will be hated for my name's sake, they will send out false lying prophets and they will find ways and reasons to eventual put you to death (this is why one disciple, elsewhere, asked about John who was no doubt told he would never be put to death and Jesus basically told him to let him worry about that). Jesus tells them that sin and iniquity will abound and many people's love would wax cold. He tells them that, AND THEN RIGHT AWAY says, but only he who ENDURES UNTO THE END will be SAVED !! Thus he is warning them not to punk out as we would say it, keep the faith to the very end even when they threaten you with death. Then in verse 14 Jesus finally tells them what brings THE END (70th week)
When the Gospel is preached unto the WHOLE WORLD then and then only will the END COME (70th week).
Then Jesus goes straight into the 70th weeK with verse 15 and the AoD. The Gospel is still being preached, when the Church is Raptured, the 70th week will come, but not until after the Rapture.
In verses 15-21 Jesus is speaking about the 70th week Jesus fleeing after they REPENT and in verse 24 we see the THIRD MENTION of false ptophets/chists in that THE False Prophet and THE Ant-Christ who work miracles are mentioned at this time. So, there is a rhyme and reason to everything in Matt. 24, people for the most part just overlook it.
