Yes. I have proof for myself, but it cannot be shown to others. Knowing that God lives is achieved on a personal level. Again, read my post about Paul's natural man and how the world cannot understand things spiritually.
I repeat for clarity--the world is physically unable to discern things spiritually. You have to receive a witness from God, by the Spirit. There is no other way.
Like Paul said, "even so the things of God knoweth no man, but [by] the Spirit of God."
You cannot receive a spiritual witness or a testimony of spiritual things unless the Spirit manifested it unto you. Just like I can't receive proof of physical things unless the spirit of science or of man has shown it to me.
