It is freeing to recognize that I have never sinned and it pissed Christians off when I say this. To clarify, in Christianity sin is not simply “the bad things we do” it is specifically an offense against god. God does not exists so i have never sinned against him.
I’ve been an atheist for for 16 years but it was only recently that I realized this distinction. It short-circuits the guilt based evangelism. It forces the christian to first demonstrate that god exists before they can convince me I have sinned and need to be saved from that sin. And to say the least, they are ill equipped to demonstrate the existence of god.
A sin is a transgression against a god. I can’t transgress against something I don’t think exists.
If I break the law, I’m a lawbreaker, not a sinner. If I break an unjust law, I doubt even you would consider me a sinner.
