This is very interesting. I am an ENFP and I would consider myself agnostic, but sort of leaning towards the side of spirituality, as it resonates with me the most, although I do not have any good reason to fully entrust my faith to that belief.
I was raised in an unreligious family however. I've had a lot of Christian influence over the course of my life, and that only caused me to hate the religion even more. I feel free that I am unreligious. It's one thing my parents did right.
I don't deny the existance of a God but I see no reason not to doubt it either since it doesn't seem to affect my life either way.
