When I usually think of remission, I think of how it is applied in medicine:
A temporary or permanent decrease or subsidence of manifestations of a disease.
I hadn't associated how this connects with us spiritually - the remission of sins made possible because of Jesus Christ through baptism. It means, if it takes hold upon us, that the sins we are being forgiven of can be stopped, and we can be changed for it.
This is just one of many things I'm learning in James Ferrell's new book.
