In 70 A. D., the Jews saw their revolt against the Romans as the Battle of Armageddon. 300 years later, the Bishop of Tours claimed that the end times were going to be arriving any day now.
1,000 years later, The Black Plague was making its way around Europe, as the world proclaimed that this was certainly the end! 500 years down the line, hundreds of thousands of American Christians lined up for an event that would later be known as 'The Great Disappointment'.
Had they read 2 Peter 3, they would have realized that God takes no joy in destroying His creation, and is certainly not as fickle as the false prophecies like to imply.
Many have lived in their idea of 'end times', and have been convinced theirs will be the last. Yet God has stated that only He knows.
Our job is not to be obsessed with Mayan calendars or British star maps. God has reserved the difficult task of judgment for Himself.
All that is asked of us is that we come to repent. Everything else is but an egotistical distraction.
