...contained the definition of repentance in the strict sense from the Solid Declaration. It embraces three things:
1. Acknowledging our sins
2. Being heartily sorry for them (same language is picked up in the Confession of Sins in DS III - sorry, Dr. Korby, but that's the language of our Symbols!)
3. Stopping them
That last bit reminds me very much of the discussion in, I think, the second story in Hammer of God, where the question is put to the pastor about how one knows one is truly repentant for sin, and the pastor answers without hesitation: when you're willing to quit them. If you're not, stop pretending you're sorry.
Hard law, indeed. And it remains true that until we die, this determination to "stop them" is always weak, fragile, fickle. But it is most certainly of the very essence of repentance and without it, there simply is no repentance.
