I, personally, am not a believer in sin. I believe in mistakes that will be overturned by God's Will that shows we are perfection and anything else is unreal.
I used to believe the traditional Christian explanations of life but no longer. I am a student of A Course In Miracles and even there I have my own personal understanding of it.
Thank you for sharing your understanding at this time. Doing that allows the Spirit to continue to teach us. That has been my experience anyway.
