The Prophecy has been Given to Us Jovaro, i dont think God wants to reveal to us when and how, just like he doesn't reveal to us What day and hour he will return ... If he told us when exactly and how, Damascus would be prepared.
The idea of the Prophecies is that only the Beleivers whom God gives wisdom to can make sense out of the Prophecies if they Meditate upon it.
Just like the Book of Revelations, they're a specific way to interpret it, John wrote the book through the Holy Spirit in a symbolic and encrypted way to avoid persecution etc whilst on the Island of Patmos.
However ... Just like Jesus Prophecied several times that Israel will be re-established as Nation BEFORE he comes, Before the RAPTURE and the End Times ... he Said once Israel becomes a nation, the Signs of the Times starts, like the Countdown to Armageddon if you like.
These prophecies came true on May 14th 4pm 1948 When Israel became a Nation again
I personally dont beleive in mistakes or coincidences like this. Given the fact it will happen before Jesus returns. Do you beleive its a coincidence? I hope not
Anyway ... Isaiah 17 ... It does not mention any dates or how like i explained above, but ... I have been doing some Bible Code's research and have found words such as George W. Bush, Radiation, Nuke etc crossing over Isaiah 17.
The Scripture gives us a hint already ... "Heap of Ruins" ... Nuke's are able to do that perfectly. Melt away everything until heaps of trash are left over. Think about it. Anyway ... These times are pretty interesting. For now we need to keep watching the news.
When Damascus is destroyed i'll be the first one to let you know Jovaro
God Bless.
