Someone asked me for resources that might be helpful in a continued study in 2 Corinthians. Here are a few that I have found especially helpful over the last few months.
Paul for Everyone 2 Corinthians by Tom Wright
The Message of 2 Corinthians Power in Weakness by Paul Barnett
II Corinthians A Commentary by Frank J. Matera
Conflict and Community in Corinth A Socio-Rhetorical Commentary on 1 and 2 Corinthians by Ben Witherington III
