The ultimate test of whether one's personal experience is reliable is to ask God by having an agreement with Him that one is seeking confirmation of ones truth by a display of a message of '7' (1.15,2.41, 3.04, 4.12, 5.02, 6.10, 7.00, 8.08, 9.25, 10.42, 11.32, 12.04, etc) when one approaches a digital clock in devotion that one uses to test for Him. This is scientific because surely if God exists in reality He will have to answer with the correct reply given that all 7.5 billion human replies would have been subjective. If that reply is not sufficient, there is no God by anyone's prophecies and God remains an imaginary concept.
