I mentioned yesterday that I would highlight a number of things for the new ezine of the Alliance of Confessing Evangelicals: Reformation21.
First off, the main theme of the issue is the so-called New Perspective on Paul.
Ligon Duncan provides an overview, along with some recommended reading if you're new to the discussion.
Rick Phillips has a three-part series on the historical background and the NPP's teachings on justification and imputation.
Guy Waters reviews Carson/O'Brien/Seifrid's Justification and Variegated Nomism, vol. 2.
Jeremy Smith reviews Guy Waters' Justification and the New Perspective on Paul.
The Ref21 archives offer some sermons on justification by Bonar, Calvin, Spurgeon, and others.
