What is Sin
Sin is a way of conceptualizing our distance from God. God as knowledge, peace of mind, our ideal self, the life we know to be our will, the health we all seek to sustain.
It is NOT a justification for judging other people. If you are using the concept of Sin to judge other people, you should have dropped the concept two thousand years ago.
If you are judging others and placing your life above theirs, you are Satan.
