To bring this to a close, this writer believes most of Matt. 24 is about Israel and the Tribulation period not the Rapture, or the Church or the Church Age. Jesus answered the three questions that He was asked including the one about the end of the world (or age).
Wondering about the end times and the rapture can cause confusion, worry and fear for a lot of people, even Christians! For ages people have tried to figure out the exact time that the prophecy of Jesus’s return will happen. The best place to turn for answers about the rapture is Scripture! God tells us everything we need to know in the Bible. There are some things that God has left a mystery for us, but has given us enough information in His Word that we should have complete confidence and hope in the Hope of our Salvation. The above verses speak of a time when those who are found in Jesus Christ will stand before Him and receive what has been done in our body, either for Him, or for ourselves.
There are those who say that prophecy has been fulfilled in the year 70AD and that we are doing nothing but waiting for the return of Jesus Christ. These folks are what are called Preterist and discount prophecy as not for our time, or that we are living in the ends of days.
There are no words to describe how bad the Tribulation period is going to be; one-fourth of earth’s population will die (Rev. 6:7-8); one-third of those who are left will die (Rev. 9:13-21).
My own studied and prayerfully considered opinion is that while threats (rumors) of war and even hostilities like we are witnessing from ISIL, Hamas, and occasionally other volatile players around the world will continue, there will be no world-rending war this side of the Rapture of the church.
