“Faith is mysterious and ineffable. It is an emotional, not necessarily a rational, experience. Religion is a fairly recent human invention. But faith, as I have elsewhere argued, is embedded in our very evolution as human beings.
“And yet, in the end, faith is nothing more or less than a choice. You either believe there is something beyond the physical world (as I do), or you don’t. You either believe you are more than the sum of your material parts (as I do), or you don’t. You either believe in the existence of a soul (as I do), or you don’t.
“No one can prove or disprove these things, not any more than anyone can prove or disprove love or fear or any other human emotion.
“Religion, on the other hand, is the language we use to express faith. It is a language made up of symbols and metaphors that allows people to express to each other (and to themselves) what is, almost by definition, inexpressible.
“After all, if there is a God, then that God is utterly beyond human comprehension.”
