He was clearly talking about his "second coming" so what is it "the end" of?
Yeshua won't officially return until all things are fulfilled, and that is at the very
end of reality its self.
Matthew 24:29-30 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: (30) And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Basically the return is a sign of the coming of Judgement day, and after for some to reign in the Messianic age.
Matthew 24:37-39 But as the days of Noe were, so shall also the coming of the Son of man be. (38) For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, (39) And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
What do you expect to see happen according to what Jesus taught?
There will be soon worldwide destruction, earth quakes, tidal waves, mass hurricanes mostly caused by human destruction of the planet; why Revelations says God will remove those who are destroying earth.
There will also be world war 3 fought over Israel. There will be mass starvation due to raising diseased cattle, where we will get global pandemics.
The verses you posted (Matthew 24:5) about people deceived by 'Ego I-mee' (I Am), and 'Eggzio' (time draws near) has already happened globally, and is the gospel of John, epistles of Paul, and Simon the stone (petros) who've misled everyone.
Basically when everything is nearly destroyed, then God will step in, and save those who are worthy to be called children of God.
Great deception, Tribulation, Second Coming, Judgement day, Messianic age.
