I am very happy to become a member of this wonderful Bible forums, so as my first post, I just want to contribute a little information about the end time prophecy and the verse is written at the book of Luke chapter 21 verse 20
"And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. " (Luke 21:20)
Remember that when our Lord speak about wisdom of God, He does not speak literally but spiritually. These armies are spiritual armies that will conquer the old Jerusalem. These Jerusalem are the nations who will destroy by the spiritual armies, who also came from the Mighty Creator.
Why Should God Will Destroy Jerusalem? Simply because, it was prophesized by our Lord himself saying,
"O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not! Behold, your house is left unto you desolate." (Matthew 23:37-38)
The Old Jerusalem was a hometown of a bunch of thieves and murderers, that is why the Father will desolate the old place. We can clearly see right now that the armies are continuing to compass the old place and I can see some armies here at Bible Forums.
To mods, hope I can put link related about this topic.
Thank You and God bless
