Are we all gonna die in 2012?

From a Christian opinion, there are many, many things that have to take place before the second coming of Christ. The Bible says that NO MAN will know the day or the time, but there are warnings against the things to come so we will know that the time is near. The Book of Revelation is very clear on what WILL happen.... there is already hunger and disease in the world, and I'm not sure what two other things you are thinking of, but there are alot more than 4 things that need to happen to fulfill biblical prophecy. I wouldn't put too much stock in the Mayans. Some Christians believe in a "rapture" *where all the believers of Jesus Christ are taken up into Heaven and spared the hell that will come to this world before Jesus comes back*..and others believe that we will be here for what is called the Tribulation period. The Bible is very clear that in the end times our earthly life will depend on our beliefs, whether we believe in Him or not. Some of us will be killed because we believe in Jesus Christ. But it's our spiritual life that we need to be worried about, not our earthly life. If you don't know about Jesus Christ and want to know more, there are people all over who would love to share the gospel and love of Christ with you.
