These verses deal with the idea of exclusion and inclusion…of belonging or being unattached…of being an insider or an outsider. Gentiles, or unbelievers, lacked the covenantal physical sign of circumcision and thus were excluded. But then Jesus Christ came teaching the New Covenant concept of circumcision of the heart. Romans 2:29 tells us, “Circumcision is circumcision of the heart, by the Spirit, not by the written code.” So those of us once far away from God have been brought near through the blood of Christ. (Ephesians 2:13)…so we who were once outsiders have now been reconciled and become members of God’s family.
