7 Therefore know that only those who are of faith are sons of Abraham. 8 And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.” 9 So then those who are of faith are blessed with believing Abraham.” (Galatians 3:7–9, NKJV)
The apostle boldly states that sons of Abraham are now identified based on faith, not flesh. This flies in the face of the belief that the nation of Israel continues to this day to be the people of God. The gospel teaches Christians are the sons of Abraham. Justification is reckoned on the basis of faith in Christ, not upon fleshly descent from Abraham. Paul later explained that “if you are Christ’s then you are Abraham’s seed, and heirs according to the promise” (Gal. 3:29). Christians are “sons of God” (Gal. 3:26). You became a child of God and seed of Abraham when you were “baptized into Christ.” That is when you “put on Christ” (Gal. 3:27). Thank God today that your salvation does not depend on your physical pedigree. It depends on Christ, and your faith to believe and to His will. As Jesus said, “For whoever does the will of God is My brother and My sister and mother” (Mk. 3:35).
