What are the limits of grace? We pressure people so much to instantly demonstrate that they are a Christian with their actions. They might have been an addict for 20 years, then trust Jesus and we think they're not going to struggle with addiction anymore, instantly, forever. Now granted, God has the ability to make that happen. But I think that is a very rare occurence.
So why do we put limits on grace. We call someone out on cussing, or drinking, or sloth and yet refuse to honestly evaluate our own lives and the sins with which we struggle. Any accountability that is going to provide for true life change is going to happen in the context of a reciprocally accountable relationship.
