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)
This is part of Jesus' Olivet Prophecy, where He predicts conditions before His return—and our redemption is still future!
The conclusion is clear: Sanctification is a process; conversion is a process; and growing and overcoming are a process. We go—proceed—on to perfection, and now we see that redemption is also a process. We do not become completely free of our captivity to Satan and this world in one giant leap. Liberty is produced incrementally, one step at a time. We are indeed the firstfruits of God's great purpose, but we are most assuredly not a finished product—yet. We are under construction, being transformed and brought "to the measure of the stature of the fullness of Christ" (Ephesians 4:13).
