No We self harmed,
Speak for yourself. I haven't self harmed.
we think doing wrong and getting away with it is advantages
It frequently does have advantages. I'm sure we can all tink of instances where people have done wrong but got away with it. These people,e do harm, but not necessarily self harm.
but as the book tells us the wages of sin is death of ourselves
We all die. This is like telling an animal that has no legs it will have to slither around on its belly for ever more.
, we harm our selves. Only Jesus can take that from us. He doesn't die because of his own wrongdoing.
He didn't die according to your book, at least, not permanently. It's like using a credit card to pay somebody's debt, then ringing the bank and reversing the transaction.
