How can you talk to an atheist about salvation? He doesn’t believe in a single component of that worldview. No God. No problem.Problematically for that assertion, the only thing "an atheist" believes about that is "No God".
This was the subject of the posts tagged "Loftus Saga" here from the end of last year -- because Loftus and many of the "new" Atheists rely heavily on the problem of evil to make their evangelistic case. In the Ricky Gervais video making the rounds this week, Ricky does it as well -- using the minimalist example of God making him an atheist.
There is something wrong with the world, and the atheist says that since God doesn't exist, you just have to live with it. The first time the atheist has trouble in fact and not just in theory, I think you're going to have a great evangelistic moment.
You might want to re-read that Loftus Saga stuff if you're thinking that atheism is making an end-run around theism by its popular appeal.
