Commentaries:
In verses 7-19, Jesus informs us about the visible signs of world events which signal that the end is near. In verses 20-24, He is still talking about these visible signs, but specifically about those that involve Jerusalem. Verses 25-28 describe the cataclysmic events in the sky and on the earth, heralding His imminent return. Thus, through verse 28, our Savior reveals to us the events presaging His return in the world (verses 7-19), in Jerusalem (verses 20-24), and in the sky and earth (verses 25-28).

Praying Always (Part One)
If we are in Judea at this time, we should flee and not expect God to protect us there. Wisdom dictates that we follow God's instruction and get out. God's purpose in our lives will be worked out somewhere else. He also warns that, if we are outside the city, do not go into it—more wisdom. Why? "These are the days of vengeance."
