The faithfulness of Christ is a recurring theme of this letter. A most necessary antidote to the formalistic tendencies of the Galatian Christians. It's nowhere more impressively shown than through the cross, the ultimate expression of his faithful love for us. Indeed, Christ’s own faithful working to God’s plan is the contrast made in this letter with the hopeless error of those who were relying on their own works to make themselves acceptable to God.
