We laugh and make jokes about this but it truthfully is so sad. The problem is that people get a warped idea of what the rapture is and all these “false alarms” make them bolder in their mocking. Some day the Rapture spoke of in the Bible , of which only God knows the day and hour, will take place and I believe there will be those that were not prepared due to people causing confusion like this.
The problem is overly focusing on the Rapture (with all the Left Behind books being as bad) and not focusing on God in our lives now. God at each service in communion with us and when we pray to Him. We ought to live each day as our last instead of focusing on when the last day will be.
