NO. that does no mean that if i pray to God to reveal himself and he doesn't that he does not exist.
Thou gavest also thy good spirit to instruct them
And we are his witnesses of these things; and so is also the Holy Ghost
But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me.
But God hath revealed them unto us by his Spirit
And it is the Spirit that beareth witness
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things
But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me
If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
But let him ask in faith, nothing wavering. For he that waivereth is like a wave of the sea driven with the wind and tossed.
Question: Does God exist?
Observation: Scriptures claim that when you pray to God in the name of Jesus Christ with the desire to know the existence of God, you will receive testimony by the power of the Holy Ghost.
Hypothesis: If I do this, something could happen.
Prediction: *insert your expectations here*
Experimentation: Pray, observe results while remembering there is no physical evidence to show for it, as everything is in your head.
