I find it deeply disturbing that someone allegedly educated to the level of a PHD in a scientific field should make this claim.
Spiritual knowledge is the same way. I can say that I know Jesus is the Christ because I have studied his life and teachings. I have asked questions and conducted experiments that have taught me through my experience that this is true. The evidence is overwhelming. I can't convey my results of this spiritual learning in a spreadsheet, but it is real nonetheless. I can only invite you to conduct your own experiment upon the word of God.
