What is the Biblical basis for saying that we won't have a second chance to be saved after we die?

A commonly held belief is that people need to accept Jesus as Lord *during their lifetime on Earth* and failing to do so will result in the individual's damnation. Is there any support for this "last call" doctrine? [Since there is life after death](https://christianity.stackexchange.com/questions/17256/judgement-upon-death#comment49358_17256) , I have wondered if people will have an opportunity to make a decision for Jesus after their death. Is there any support for this "second chance" idea? I have tried to study it and have not able to find anything in the bible that would contradict this idea that we can still make a decision for Christ after this life.
