Grappling with Galatians is a free series of podcasts by N. T. Wright, provided by Regent College (Vancouver, Canada).
While I’m not a podcast junkie, you’ll find this set helps you come to terms with what Galatians meant to the people of central Turkey who first received the letter, and therefore what it could mean for us today.
This is a college level course. The notes include Wright’s Kingdom Translation of Galatians, alongside the Greek text. While there is no financial cost, expect to invest some time in listening to and, well, grappling with Galatians.
