I think Morris' work should not go untouched when studying Romans. His work on Romans 7 is fantastic and goes close to trumping most modern commentaries except maybe Moo in this regard. His work is excellent throughout. You may not come out agreeing with all his analysis on Romans but he is solid all the same.

Students of Scripture should read anything they can find by Leon Morris, and his commentary on Romans is no exception. Morris is always careful and considered in his judgment. Highly recommended. [Full Review]
