The driving theme of the book of Galatians is the glory of Christ—the glory of his perfect obedience to all the requirements of God’s law. Driven by unbreakable certainty in his calling as a herald of divine truth to the churches in Galatia, the apostle Paul fearlessly declares that Jesus Christ alone saves. The joyous life that might be found through obedience to the law has been taken away by human sinfulness—only Jesus has kept every positive requirement of the law and has even suffered its curse. The result is that union with Christ by faith is the triune God’s provision for sinners to be declared right by him—the Father calls; the Son saves; the Spirit draws.
