Bottom line...

The true hope of an atheist is that there will be no life after death. This world is all there is so we better make the most of it.
The true hope of an agnostic is we just can't know anything for sure, so we may as well be the best we can... just in case!
The true hope of the religious is that all the good things we do in this life just might buy us a better place when we get to the next life. This goes along with most of the world's religions, no matter what their view of the afterlife is.
The true hope of a Christian is everything depends on Jesus. He claimed to not only speak the truth but to also be truth itself, with all events of his earthly life confirming what he spoke and did. Living for him is not only better in this life but also in the life to come... by far!
