The strong tendency of the Galatian Christians to depend upon ceremonies or upon legal obedience, in addition to their faith in Christ, elicits in this chapter a magnificent demonstration of the simplicity and sufficiency of faith alone.
Faith had underlain the commencement of their Christian life, Gal 3:1-5. They had found peace with God through faith. Through faith they had received the fullness of the Holy Spirit. As they had begun, so let them finish!
Faith had been the means, too, of Abraham’s acceptance with God, Gal 3:6-10. From the first the gospel of faith had been proclaimed to him by the divine Spirit. Long before he had become a Jew by the initial rite of Judaism, he had been a humble believer in God’s promise, on the basis of which he was reckoned righteous. Simple faith was the only condition that he had fulfilled, and the promise that all flesh should be blessed through him had been given when he was still a believing Gentile. Surely what had sufficed for the father of the faithful was good enough for his children! Let each reader see to it that he does not merely believe about Christ, but believes in Him, so as to be no longer under the curse, but within the blessing.
