That's a pretty good summary. I do find some minor flaws in the slide's exegesis
(Romans 4:5 does not actually state the gospel is unconditional). For those interested in more on the subject of Law and Gospel there is an excellent comparative work in the Counterpoint Series on this subject, "
Five Views on Law and Gospel." There is a "modified" Lutheran viewpoint contributed by Douglas Moo. It's worth noting that since the Law testifies about Christ (Lk. 24:44; Jn. 5:39) it also shows us the prescription for the affliction, but it is "veiled" in figures of speech, typology, and allegory and in need of further revelation, such as that which occurred in the incarnation. I've used the SOS acronym. Wasn't aware it was a Lutheran thing.
