Thank you for your comment. Dad was not a Preacher, he just preached to people what he thought was the true meaning of the Bible. It is funny what you said about the Old King James version, if I remember correctly, that is the version he said was the most true.
I wish I had not learned to tune him out and now I would understand what he was trying to tell me and the meaning behind this song. It makes sense what you said 'Birthmark' on listening to the song I would interpret as our flaws which each has.
