We’ve recently been enjoying three outstanding new commentary releases that should be on the radar of pastors preaching in these texts:
James by Craig L. Blomberg and Mariam K. Kamell, part of the Exegetical Commentary on the New Testament series from Zondervan;
Jude & 2 Peter by Gene L. Green, part of the Baker Exegetical Commentary on the New Testament;
The Acts of the Apostles by David G. Peterson, a hefty addition to the Pillar New Testament Commentary series from Wm. B. Eerdmans.
