24-25 As Isaiah said in the days after that great suffering,
The sun will refuse to shine,
and the moon will hold back its light.
The stars in heaven will fall,
and the powers in the heavens will be shaken.[a]
26 Then you will see (as Daniel predicted) “the Son of Man coming in the clouds,”[b] clothed in power and majesty. 27 And He will send out His heavenly messengers and gather together to Himself those He has chosen from the four corners of the world, from every direction and every land.
The disciples can’t help but notice that something is in the air during this week between His entry into Jerusalem and His crucifixion. Surely the moment when Jesus is to reveal Himself as the Anointed can’t be far off. By repeatedly calling Himself the Son of Man, Jesus has told people His kingdom will be divinely instituted like the one described in Daniel 7. They are also thinking of promises about the coming Anointed One. But for Jesus, everything now is connected to His imminent death and resurrection. Even as He predicts the temple’s fall—an event that will occur about 40 years later—and speaks of His second coming, He is still thinking about His death. After all, resurrection can’t happen without death. And the old world must die before the world is made new.
Jesus: 28 Learn this lesson from the fig tree: When its branch is new and tender and begins to put forth leaves, you know that summer must be near. 29 In the same way, when you see and hear the things I’ve described to you taking place, you’ll know the time is drawing near. 30 It’s true—this generation will not pass away before all these things have happened. 31 Heaven and earth may pass away, but these words of Mine will never pass away.
