No, 2012 probably won't be the end, or we should suspect 2012 of being the end no more then we should expect 2009 to be the end, or 2010, 2011, 2013...you get the picture.
Read onward for perspective-

There is a war on, 24/7. You have an enemy that does not sleep and has no mercy. This enemy's only purpose in existence is to destroy you and all that you love. This enemy is smarter and stronger than you will ever hope to be. The worst part is, this enemy is hidden. It's greatest weapon is convincing you that it does not even exist. Yet there is power that this enemy can't touch, and that power is your only hope. That power is Jesus Christ.
