I been watching Hal Lindsey for years and you really get a good picture of just how prophecy is being fulfilled. One thing the bible mentions is how there will be great earthquakes in diverse places. Remember before tv and internet and satellite most people weren't aware of natural disasters happening all over the world. Now we can know about those great earthquakes and in diverse locations instantly. Secondly many of the large earthquakes have been happening since israel became a nation. In fact in the last 50 years the top 3 largest earthquakes and worst tsunamis and most of the largest earthquakes ever were recorded. God also said it was like birth pains and it seems to be intensifying. We had the Indonesia tsunami in 2004, japan earthquake and their devastating tsunami in 2011, the big chile earthquake in 2010 and the massive killer earthquake in haiti also in that same year. Hal lindsey talks about how the clock started ticking after 1948 when Israel became a nation. Another thing is the middle east unrest seems to be intensifying the last few years and even moreso the last few months with libya, egypt, syria, Iran, and many others.
