Now and before.

The special case is what I would go for, in terms of the existence.
That's why we can't define God; only he can define himself.

I think you mean 'special pleading', not 'special case'.  Special pleading is a logical fallacy.

If we can't define God, then we can't even think about God, it's as simple as that. Try to think about anything - poetry, a cheese sandwich, a duck, anything at all - without having defined it first.
