Bush is isolated, alone with his God.

Stelzer said Bush seemed smarter than he expected. The conversation ranged from history to religion and touched on sensitive topics for a president wrestling with his legacy. "He asked me, 'Do you think our unpopularity abroad is a result of my personality?' And he laughed," Stelzer recalled. "I said, 'In part.' And he laughed again."

Much of the discussion focused on the nature of good and evil, a perennial theme for Bush, who casts the struggle against Islamic extremists in black-and-white terms. Michael Novak, a theologian who participated, said it was clear that Bush weathers his difficulties because he sees himself as doing the Lord's work.

"His faith is very strong," said Novak, a scholar at the American Enterprise Institute. "Faith is not enough by itself because there are a lot of people who have faith but weak hearts. But his faith is very strong. He seeks guidance, like every other president does, in prayer. And that means trying to be sure he's doing the right thing. And if you've got that set, all the criticism, it doesn't faze you very much. You're answering to God."

Is there really a more frightening concept then the idea of a man completely cut off from reality and seeking solace from an imaginary being, in control of the most powerful country in the world?
