Yes, it is faith that saves, and that even comes “by grace” in that it is a gift, so no one can boast. But in being reconciled to God, we come to see sin for what it actually is, rather than how we too often see it, as Satan wants us to - harmless, unavoidable, our choice, even enjoyable and “good.” Evil becomes good. But in becoming new creatures in Christ, if we have, then sin grieves us as it does God, and our concern then is not wanting to grieve Him and harm others and ourselves by doing it.
