Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

The more spirit the less form
The more spirit the less form. Content increases as form lessens. In total form (logic) each sentence has no content (the sentences of logic are just A, B, C and you can fill them with anything) then science has more content but less formal logic behind it. Then morality and ethics has even more content (people and the meaning of life) the God is beyond logical form (even the impossible is possible) but total content.
So in this context I would say that the religious world in as much as it stresses halacha [law] loses spiritual content
