First off, let's begin w/ sin. If you don't believe sin is an objective stand alone concept that actually exists, all your other comments really don't have anchors..
So ... do you believe sin is real?
Yes.
Sorry it took me a while to reply to you earlier. If you don't mind, I'd like to continue our discussion.
You claimed that if evolution is true, there is no sin. I asked you why you think that follows, for I don't see it.
You then asked me if I believe if sin. I answered yes.
Would you mind, then, explaining to me why you think evolution implies there is no sin? I'd really like to know the basis of your reasoning.
