Well, that was both stimulating and exhausting, a secular Jew with a vast knowledge of history and literature debating the rock star atheist Christopher Hitchens!
Hitchens' most serious objection to Christian theology is the substitutionary death for sin which is of course the central doctrine of the faith. He sees it as an abdication of personal responsibility, without proposing a reasonable alternative to the destructive consequences of human sin. Unforgiven and incapable of forgiving, he is stuck in the super-glue of bitterness. It literally drips from his words.
Futility. The Holy Spirit does not come through the mind, He does satisfy the mind, but of necessity first attacks the heart. Sin is known in the conscience, and the unregenerate must manipulate and rationalize to maintain contact with the rational world. The regenerated man has a new mind, and the Holy Spirit easily resides there in truth and harmony. The things of God are reasonable and fulfill the human mind with wisdom.
Ah to join the Psalmist in his revelations in the sanctuary of God! (73) He goes in as one man, comes out as a whole new man!
Hitchens is unregenerated, proudly so of course. None of what we know in our regeneration makes sense to him, and years of eloquent humanistic thinking have isolated him in pride and delusion. I doubt he would visit us here.
Ultimately, science can not save these people, as they are trapped in the laws of entropy like everyone else. They grow old, their bodies deteriorate, their health-preserving efforts disappointingly weak. And all the while they cannot explain how those same laws that demand that complex systems break apart at one time came together with miraculous precision to make life with the power to reproduce itself! When did the laws of complex creation and entropy do the 180?
It's really quite simple, Mr. Hitchens. Love is the preeminent characteristic of a triune God. He knew love before He created anything, and infused everything He made with it. It should be no surprise that He made men free to sin if they pleased, and made a safe and rational provision to save them while upholding the integrity of His Governance of the universe. With what kind of audacity should you or I pass judgement on the creator's kindness?
I still maintain that to believe in atheism I would have to believe that I created the heavens and the earth myself without help or prior experience.
My recommendation would be the sanctuary of God. There are wonderful things to learn in there.
