These signs they say are related to Israel & and then there will be nothing like it for the rest of the 21 century which will be until December 31, 2100. Thats a long way off If these signs are significant and do have meaning? Just things going on as they are now in the world & still going on like that till 2100 is highly unlikely. So what will be coming between now and then?
