As a Christian I agree that much of the article is flawed on logic. However I do think the conclusion has some merit. That most atheists do not live as though life is the accident that they claim it to be. However some do indeed live that way.
"The atheist is irrational because he has no other choice – because the rational consequences of his non-belief are simply too terrible to bear."
I do think the Atheist is irrational, but not because he disbelieves what I claim to be true without proof. But I believe that God provides the Atheist with ample proof and is rejected by the Atheist. But I take it on faith that this occurs because 1) God has provided me sufficient proof and 2) I know God well enough to believe that He is serious when He says he desires nobody to perish.
God doesn't manifest His presence in such a way that His existence is obvious and incontrovertible to everyone. Doing so might leave you with little choice but to worship Him. Certainly it would be hard to argue that you chose to love God or obey Him when His alpowerful Holy presence is constantly around. But that does not mean that He doesn't provide ample proof on an individual basis.
I think you should recognize the contradiction there. “Proof” is not subjective. Either God’s provable or not.
I’m not able to invest the time here to rehash the evidence supporting or contradicting the Bible. But I hope to never be so arrogant and insulting as to publicly accuse all those that disagree with me of being “irrational”.
