I don't in any way need to say "70ad" to prove preterism is true. All I need to do is point to what Jesus told the apostles with a basic understanding of what a personal pronoun is.
Speaking to His apostles
Luke 21:20But when
you see Jerusalem surrounded by armies,
you will know that her desolation is near.
21Then let those who are in Judea flee to the mountains, let those in the city get out, and let those in the country stay out of the city.
22For
these are the days of vengeance, to fulfill all that is written.
23How miserable those days will be for pregnant and nursing mothers! For there will be great distress upon the land and
wrath against this people. 24They will fall by the edge of the sword and be led captive into all the nations. And Jerusalem will be trodden down by the Gentiles, until the times of the Gentiles are fulfilled.
25There will be signs in the sun and moon and stars, and on the earth dismay among the nations, bewildered by the roaring of the sea and the surging of the waves.
26Men will faint from fear and anxiety over what is coming upon the earth, for the powers of the heavens will be shaken.
27At that time they will see the Son of Man coming in a cloud with power and great glory.
28When these things begin to happen, stand up and lift up
your heads, because
your redemption is drawing near.”
Now there's an opinion that contradicts the bible. Jesus called it "His Father's House".
Hebrews 9:
25Nor did He enter heaven to offer Himself again and again,
as the high priest enters the Most Holy Place every year with blood that is not his own. (Stated in the present tense.)
And let's not forget what Jesus said: Luke 13:35Look, your house is left to you desolate. And I tell you that you will not see Me again until you say, ‘Blessed is He who comes in the name of the Lord.’ ” Who was He speaking to when He said "you"
