Our Lord told us not to be troubled, because these are only the beginning of "birth pains" [Matt. 24:8]. I believe that God is warning the world. The world has broken His covenant and has gone away from Him and these events are warnings designed to turn us to Him. And what we have seen thus far is just a prelude. The warnings are going to continue during the next few years, even building in intensity. After these warnings, the real judgment is going to come.

"So when you see standing in the holy place 'the abomination that causes desolation,' spoken of through the prophet Daniel--let the reader understand-- then let those who are in Judea flee to the mountains. Let no one on the roof of his house go down to take anything out of the house. Let no one in the field go back to get his cloak. How dreadful it will be in those days for pregnant women and nursing mothers! Pray that your flight will not take place in winter or on the Sabbath. For then there will be great distress, unequaled from the beginning of the world until now--and never to be equaled again. If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened. At that time if anyone says to you, 'Look, here is the Christ!' or, 'There he is!' do not believe it. For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect--if that were possible. See, I have told you ahead of time. "So if anyone tells you, 'There he is, out in the desert,' do not go out; or, 'Here he is, in the inner rooms,' do not believe it. For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. Wherever there is a carcass, there the vultures will gather. - Matthew 24:15-28
