There are God's judgements found throughout the Bible that have fallen on the enemy and during the sounding of the first six trumpets are more judgements against the enemy clear up to the time they are made the footstool of Christ. There have been many abominations and the last one will be the son of perdition taking his seat on the very Temple Mount of God and that is what we are to flee from so we are not forced into taking the mark of this beast out of the earth.All of Matthew 24 preceding when the Christians were warned to leave. Those who pierced him saw the judgement of God for crucifying Christ. After verse 31, no more great tribulation described. Jesus have more detail in Revelation. But his second coming has not occurred yet. The kingdoms of this world are becoming the kingdoms of our Lord.
When Jesus sat on the Mount of Olives talking to His disciples that day in Matthew 24 there were no Christians at that time but only the Israelites/Jews as the day of Pentecost had not yet happened. The disciples asked Him three questions: Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world? Did the world end in 70AD.........no, so these were all future events. Even the destruction of Jerusalem in 70AD
