do you believe that year 2012 is the end of the world?

I agree with you. There is not one who knows what the end of the world will be but God, who shapes the world in His hands. Those predictions of men had been here long before us but all of them have erred in predicting the end of the world. It's a waste of time. The most important in life is the salvation of our soul - knowing where to spend eternity.
