If it is going to happen in 2012, I don't know. I believe in what the Bible says:
And he said, Take care that you are not tricked: for a number of people will come in my name, saying, I am he; and, The time is near: do not go after them.
And when news of wars and troubled times comes to your ears, have no fear; for these things have to be, but the end will not be now.
Then he said to them, Nation will be moved against nation and kingdom against kingdom:
There will be great earth-shocks and outbursts of disease in a number of places, and men will be without food; and there will be wonders and great signs from heaven. Lc 21:8-11
Jesus shows us some tips about when these things will happen, however he said clearly:
But of that day or that hour no one has knowledge, not even the angels in heaven, or the Son, but the Father. Mc 13:32
what if it was confirmed, I think no one else can change it. If so, live every day as if you were to live your last day, enjoy yourself!Hug your friends and relatives!Be happy!! But seek first the kingdom of God and His righteousness, and all these things shall be added to you.
