Jarvis Williams' commentary on Galatians is a commentary of one of Paul's most rhetorically charged and polemically sharp letters. Williams writes a commentary of the letter, not a commentary of commentaries. He grounds the letter in grammatical-historical exegesis, seeking to help readers understand Paul's Greco-Roman and Second Temple Jewish context of the letter. Additionally, the book seeks to move from exegesis to application in a few places in the commentary. The strength of the commentary is that it offers a lucid and concise exegesis grounded in Paul's first century context and applicable for twenty-first century readers.
