The best (and only real) preparation is falling into the hands of our loving Lord and Savior Jesus Christ who is coming soon to take us out of here before He brings this judgment on the world. If you haven't received Him as your Savior, why not do it now? Just ask Him to come into your heart. It's that simple - but the results are profound because His death on the cross made it all possible by His grace.
People using religion as an excuse not to prepare are as bad as liberals nitwits. One is waiting for God to rescue them from something they should have planned for and the other is waiting on the government to rescue them.
