Since I brought it up I figured I would supply the link to the prophecy called The Last George.
The first George was a tree, the last George is a bush. A little play on words by the Holy Spirit.

This vision or word was from 1988 to David Stewart a christian evangelist. He thought it was re Bush senior but Clinton was elected instead. But another Bush appeared with the same first name who barely won the election. Is this the last year of the United States? Not much longer to find out. The letter by Steve Berryman re the US being the bush that gives forth a deception and division to Israel and will burn brought this back to mind. Maybe you should read the whole thing.

If anyone still has any doubts about the bush, turn to Job 30:1-10.  Job is speaking as a righteous and good man surrounded by evil men.  It is a passage in which Job speaks to the children of fathers his age which he would have disdained.  Note (KJV) particularly verses 4 & 7-8 that vile, base men dwell in the bushes (note plural).  Job says of these children that they abhor him and spare not to spit in his face.  He laments that he has become their song, their byword.  (I would think this has great application to the Christian people in both the US and world today....and it will get worse.  These vile, base children are our political and other leaders.)   

 

I do believe this is why the bush is a sign of the rapture, i.e. the division or separation, even from the time of Moses when the angel's appearance as a flame in the bush set in motion the deliverance of the Israelite children from bondage.  (Note: it was the fact that the flame did not harm the bush which caught Moses' attention, Exodus 3:2-3)

 

In Deuteronomy 33, we see Moses' blessing to the tribes of Israel.  Moses takes the blessing of Jacob on the tribes (Genesis 49) and further expounds upon it.  (Note: Genesis 49:1 says these blessings are for the last days, therefore so was Moses' blessing.) 

 

In Deuteronomy 33:16, we see the bush is found in the house of end time Joseph.  It mentions the blessing falling to him of goodwill that dwelt in the bush.  Then it mentions the blessing which shall fall on the head of Joseph because he lived separate.  Go back to Jacob's blessing on Joseph in Genesis 49: 26 and we see that Joseph is to wear a crown on his head because he lived separate.
