Scot McKnight, author of the Jesus Creed (which is on my reading list for the summer), has written some good thoughts on justification, salvation, and reconciliation.
My thought, though, is I wonder if the authors of the Scriptures and early Christians parsed each idea so much like we do as modern Christians. It seems that the way we take apart and parse these ideas stems from the enlightenment project and scientific study methods.
I wonder if each word overlaps and contains the other, so that you cannot have one without the other. Sometimes it seems that the ideas are held in tension, such as the idea that the kingdom has come, but not fully.
