Christianity was from the beginning, essentially and fundamentally, life's nausea and disgust with life, merely concealed behind, masked by, dressed up as, faith in "another" or "better" life.
To justify Christian morality because it provides a foundation of morality, instead of showing the necessity of Christian morality from the truth of Christianity, is a very dangerous inversion.
If 'god' is a metaphysical term, then it cannot be even probable that a god exists. For to say that 'God exists' is to make a metaphysical utterance which cannot be either true or false. And by the same criterion, no sentence which purports to describe the nature of a transcendent god can possess any literal significance.
But amid much elegance and precision, the details of life and the Universe also exhibit haphazard, jury-rigged arrangements and much poor planning. What shall we make of this: an edifice abandoned early in construction by the architect?
In this world him who does not abandon himself the Almighty will not desert. Him who helps himself will the Almighty always also help; He will show him the way by which he can gain his rights, his freedom, and therefore his future.
Theism is so confused and the sentences in which "God" appears so incoherent and so incapable of verifiability or falsifiability that to speak of belief or unbelief, faith or unfaith, is logically impossible.
