Worldwide Earthquakes from Past 7 Days (USGS)
Livescience.Com ran an article called, "Chile Earthquake: Is Mother Nature Out of Control?" that has been picked up by several other media sources. The USGS estimates there are over 1 million earthquakes a year, most of which we do not feel. The article below states that some scientists do believe that there is an increase in the number of earthquakes over the past 15 years. Of course, several large earthquakes in the span of a few weeks makes people become aware of earthquakes.
When the Lord's disciples asked him when he would return, Jesus said there would be, "earthquakes in various places" (Matthew 24:7) but "these are the beginning of the birth pains." (Matthew 24:8)
When we heard the sound of the earthquake in Jimini back in January 2010, several described it as the sound of fright train. I thought it sounded like a howl. It reminded me of Romans 8:22, "For we know that the whole creation thas been groaning together in the pains of childbirth until now."
Whether Christ's return is today, tomorrow, or a thousand years from now, the earthquakes as he said should remind us of his return. In the season of Lent, these signs of his return should cause us to repent. This is not a point your finger at someone else telling them to repent, but you and me should repent of our own sins and then seek comfort in the forgiveness found in the cross of Jesus.
