A response...

The idea of no afterlife is consistent with atheism. That much is true. But stating that morality would be of no concern to an atheist, is totally irrelevant to any discussion about afterlife. Any attempt to correlate morality with afterlife makes me think that your sole purpose in life is to expect god's approval, especially if the statement goes as follows...

"If you don't believe in God then you have no hope in any case and morality should not be an issue for you"

I find your rationale really strange for devoted christians... It's like admitting that if you didn't expect god's approval in the end, you wouldn't be morally wholesome... If you find it perfectly natural for a non believer, it means it's perfectly natural for you under certain circumstances. Perhaps I cannot really get you, but doesn't christianity supposedly teach NOT to expect something in return and be a sincere altruist?

After all, morality is of the utmost importance to many atheists. And that's because morality has in reality little to do with belief. Much more important indeed are moral values for everyone who does not believe in an afterlife, as they want to live their only chance in existence in the best way possible. Thus, morality assumes a far more practical role... It keeps societies alive and working...
