God’s existence can only be proven with seven senses. In addition to 5 senses(touch, feel, sight, hearing, taste,smell) , self- and God-consciousness are extra senses in order to experience God. Unless, one is born again, the person cannot be God-conscious. Becoming born again is an activation of the regenerative growth and development that would occur at the heart and mind of a believer.
Unless one is God-conscious, the person will operate within a bounded space of possibilities. That is, there are possibilities one would experience until the person believes. I believe God through experiences. My preoccupation is not whether God exists; but how might I please God.
