that is one reason i have a hard time fitting a millennium anywhere into jesus' end time teaching...
It's really not that hard.
The Olivet discource ie matt 24 is about the end of the age, not the end of the world.
The age being the Jewish age and the beginning of the Messianic age.
With the destruction of the temple system it was 100% clear that the old age of sacrifices was over.
Many people interpret Matt 24 as the end of the world and not the end of the age because of this...
30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth[c] will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory.[d] 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
Coming on the clouds is Bible speak for God showing up to judge. He did just that in AD70.
The angels being sent out to gather the elect is thought by many to be angels snatching people up to heaven. But that greek word can also be translated messengers.
So it could read 'and he will send his messengers with a loud trumpet call, and they will gather the elect from the four winds, from oen en of the heavens to the other."
With the Jewish persecution hindered, the Christians had a clearer path to going out and preaching the gospel! His messengers are preachers of the gospel who preach. THe gathering is those preachers going out, preaching and gathering in those who believe.
Also notice the trumpet reference. That fits in nicely with the festivals you mentioned somewhere else.
So Mattheew 24 is about the judging of Jerusalem, ending of the age and the preaching of the gospel as it gathers in God's elect.
I believe this was the beginning of the 1000 years. Christ reigning in heaven with the tribulation saints who died during the persecution, as the gospel is advancing on the Earth!
The second coming aka end of the world doesn't come until Revelation 20:7 and onward.
The end of the world doesn't conflict with Matthew 24, because Matt 24 isn't about the end of the world!
