The only theism worthy of our respect believes in God not because of the way the world is made but in spite of that. The only theism that is no less profound than the Buddha's atheism is that represented in the Bible by Job and Jeremiah.
Faith means intense, usually confident, belief that is not based on evidence sufficient to command assent from every reasonable person.
To try to fashion something from suffering, to relish our triumphs, and to endure defeats without resentment: all that is compatible with the faith of a heretic.
