Please understand that I am not ascribing to these different theories on the end of the world in 2012. I do ascribe to the Bible which says that someday this world will suffer something catastrophic and Jesus will return to be with His people forever. However the Bible does not give us a date for these things to take place and goes so far to even say that even Jesus doesn’t know the day or hour.
That said, these theories are interesting and we should know how to speak with people about them. I would suggest that we in the Christian Church will have a great ministry with people concerned about the many theories of 2012 being the year of world disaster.
