Having very briefly touched on Colossians 1 (and to be fair his point here wasn’t to do a full argument from there, only to show different ways the Bible talks about what was accomplished on the cross), Rob moves to Romans 3 where Paul writes that we’ve been justified by grace through faith in Jesus. That’s a legal metaphor from the world of courtrooms and judges: we’re guilty, standing before the judged with no hope, except for Jesus Christ, Who pays our price and sets us free. (I will mention here that this is not very obviously what Romans 3:21-26 says, but Rob is certainly reporting a common interpretation of what it means.)
But then there are also battle images of victory and destruction, provided by Paul and John (for example) in 2 Timothy 2 and 1 John 5 (respectively).
And there are the times (such as in Ephesians) when what happened on the cross is expressed as “redemption” which is financial accounting language.
BUT ALL THOSE MEANINGS MEAN ONE THING ULTIMATELY, EXPRESSED IN DIFFERENT WAYS!
I tend to agree, and I suspect Rob does, too; but he doesn’t go out of his way to nail down (or nail up!) that one common meaning.
YOU SUSPECT…?
In his final list of New Testament meanings, he adds one to the end which isn’t actually a cited image from the NT, and which isn’t at all a metaphorical description, but is a theme common to all the others:
“enemies being loved”.
