“When you see ‘the abomination that causes desolation’ standing where it does not belong—let the reader understand—then let those who are in Judea flee to the mountains. Let no one on the housetop go down or enter the house to take anything out. Let no one in the field go back to get their cloak. How dreadful it will be in those days for pregnant women and nursing mothers! Pray that this will not take place in winter, because those will be days of distress unequaled from the beginning, when God created the world, until now—and never to be equaled again. Mark 13:14-19 NIV
Some believe that in Mark 13:10-22 Jesus is speaking of the destruction of the Jewish temple and the captivity of the Jewish people by the Romans which occurred in 70 AD. I tend to believe instead that He is speaking of the end of times. Notice that in verse 10 Christ speaks of the gospel being proclaimed to all nations of this world. That certainly did not occur in 70 AD. Although there was much distress during the time of the destruction of the Jewish temple and the captivity of the Jews, there certainly have been more distressful times in history since that event occurred. The abomination is the appearance of the antichrist, which has not yet been recorded in history.
We do not know when the end times will be. We must live our life every day for the Lord and not be concerned as to when the end times will come. Our focus is to be on serving God. He will take care of those who belong to Him, protecting them from the evil of this world.
