What does the Bible say about being the true circumcision?

In Philippians 3:3, Paul asserts that we are the circumcision, meaning that true belonging to God's people is characterized by a circumcision of the heart. This spiritual transformation, as outlined in Colossians 2:11, indicates that circumcision is not about the external cutting of the flesh, but rather a work of God in the heart, removing the filth of sin and granting faith in Christ. The focus is on worshiping God in spirit and truth, recognizing that our confidence is found in Christ alone, not in our fleshly efforts.
