You must not believe in God. He is the Way, the Truth and the Life. The ultimate in Truth, Goodness and Beauty. The Absolute of all Virtues. He is not negotiable or “within us” as though we can decide what His definition is. God is God and we are not. His existence is not subjective as though our perception of Him depends on us. He existed before Time and will exist whether we acknowledge Him or not. Truth absolutely is “out there.”
Of course He is the ‘way, truth, and life.’
The only reason we are here is because God expressed himself into matter, and Made us for a purpose that He had in mind.
We are made of Him - there’s no other way that we could possibly exist.
YMMV
