I think that every era is unique, particularly this one. While I understand that people throughout the centuries have thought that Jesus would come back in their lifetime, it's certainly true that the odds grow with each year and each generation. Also, basically the whole world is now populated and foreign relations are tense. Israel being acknowledged as an official nation in 1948 was a HUGE event as far as a biblical timeline is concerned. I could never guarantee when Jesus would return, but if you read Dr. Jeremiah's book, you will certainly see at least how things that are going on right at this moment certainly fit into biblical prophecy, particularly prophecy that approaches Christ's time of return.
These times are quite different
