Luke 21:20-36-The sure sign that Jerusalem is about to be destroyed will be armies surrounding it. Jerusalem will be attacked the entire time that the Gentiles are in power...until "the time of the Gentiles be fulfilled" (:24-this is a reference to the time period which began in 587 B.C. when the Babylonians conquered Jerusalem and extends until the days of the tribulation period, cf. Revelation 11:2).
What is “the time of the Gentiles”?
There will be many cosmic events during this time...then "they will see the Son of Man coming in a cloud with power and great glory" (:27-this is the Second Coming of Christ at the beginning of the seven years of the Tribulation). At this point, redemption is near. Jesus says that when you see trees in bloom you know that summer is near...even so, when you see these things happen you will know that the kingdom of God is near. The generation that sees the things mentioned here will still be alive at His return. "Generation" does not refer to the people that Jesus was speaking to, but to the people who see the things He has been talking about. Jesus tells them to not waste their lives...but to be prepared to face the terrible things that He has spoken about.
Luke 21:37-38-Jesus taught in the Temple during the day..."all the people would get up early in the morning to come to Him in the temple to listen to Him" (:38). He spent the night on the Mt. of Olives.
Prayer: Lord, don't let me be caught up in the mundane matters of the world. Help me to live expectantly, looking for You to return at any moment.
