Circumcision

Definition: Circumcision is the practice of removing the foreskin, usually performed on boys on the eighth day after birth. In the Bible, it was instituted as a visible sign of the covenant between God and Abraham, marking the belonging of the people of Israel to God.
Genesis 17:10-11: “This is My covenant, which you shall keep, between Me and you and your descendants after you: Every male among you shall be circumcised. And you shall be circumcised in the flesh of your foreskin, and it shall be the sign of the covenant between Me and you.”
Romans 2:28-29: “A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code.”
Explanation: Circumcision symbolizes God’s covenant with Abraham and his descendants, setting them apart from other nations. This outward sign reminds them of their commitment to live in obedience to God. In the New Testament, however, the focus shifts to “circumcision of the heart,” which means an inner transformation through faith, made possible by the Spirit. Thus, it becomes a metaphor for spiritual commitment, emphasizing that true belonging to God is inward, marked by sincere faith and a transformed life.
