“No, Jesus wasn’t speaking to ‘us’ He was speaking to the generation that would see the abomination of desolation set up, the Tribulation generation.”
If Jesus meant a generation other than the one He was speaking to, He would have said “they,” not “you.” He would have said “that generation,” not “this generation.”
Nobody speaks that way; so why change the meanings of Christ’s words?
No one is changing anyone's words.
Christ was speaking prophecy and used 'this' to refer to the group He was speaking about, the generation that would have to flee when the anti-Christ came into the Temple.
It wasn't Christians He was speaking about since Christians would not be concerned about fleeing on the Sabbath!
It is referring to the Jewish People as a whole.
See how the word generation is used for the church in 1Pe.2:9,
but ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people;
Thus, the Lord was promising the Jewish people (this generation) would not pass, it would survive, as a people, to see these events fulfilled.
