We have noted the recent increase in earthquakes, and commented on the unusual places they are happening like Illinois, Reno, etc... We have also been watching the increased frequency of severe weather like cyclones killing thousands, tsunamis killing hundreds of thousands, tornadoes killing dozens, and hurricanes destroying entire cities. The Lord tells us these are the birth pangs to watch for. The bible tells us that the earth will go through an INCREDIBLE upheaval during the tribulation and then again at the end of the 7 yr tribulation when Christ actually returns to earth to usher in the millenium. What we are seeing (I believe) is the shadows of these future events casting over our present day. It is a time that the Lord is using to wake up his followers and also to bring in others who are maybe on the edge of belief.
Going back to strange earthly occurences, this article on the Chile volcano caught my eye. http://uk.reuters.com/article/worldNews/idUKN0646185520080506 This paragraph near the end was of special interest;
"Chilean authorities were caught off guard by the eruption of the 3,280-foot (1,000-meter) volcano, long considered inactive. Officials say the volcano had been dormant for thousands of years before Friday."
The bible says that the whole world will be caught off guard by the Day of the Lord. Just like this looming volcano, the wrath of God has been dormant for thousands of years but when it finally breaks out, it will be nothing like the world has ever seen.
