I would think that the only thing you can do is pray for the best. If the world is going to end, you can't really stop it. So it's best to say your prayers and hope for the best.

as far as i know, end of the world or the Apocalypse is coming but don't know when... as far as bible tells us nothing of sort of a date and as far as prediction goes, not all can be exact... so I'd say, live on until its the end of Your story, don't mind all those prediction says or what the bible says of whats to come, just continue your story till the end of it.. since every beginning always have an ending, so the world also has its ending(it may be tomorrow or trillions and billions and trillions years to go).....
