O'Tink! ...you are something of a biblical scholar! Yes, I am not surprised those are from Isaiah, along with NT John, prolly the books I appreciate most...they tend to inspire/enhance one's own direct experience!
(sigh) to me, however, religion gets off-track when they try to substitute "instruction" for direct experience...not really promoting Dawkins here, I have NOT found him to be a clear thinker...
