Circumcision was a requirement for male Israelites under the Law. However, the ordinance preceded the law and was first practiced by Abraham. When Jesus, their promised Messiah, fulfilled the Law, the Law came to an end and the aspects of the promises to Abraham came to fulfillment. (Matthew 5:17, Colossians 2:13-17) But Christian believers are not required to be circumcised in the flesh. So, what is meant by the “circumcision of Christ”?
Romans 2:29, “…circumcision is that of the heart, in the spirit, and not in the letter…” Literal circumcision cut off the flesh. Similarly, spiritual circumcision involves the denial (cutting off) of our flesh and its desires in order to serve God. “Circumcise therefore the foreskin of your heart…” Deuteronomy 10:16. We are to circumcise our natural hearts’ desires and are to seek the spiritual with heavenly hopes. “For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.” Philippians 3:3
Remember: Self-denial is essential to be a follower of Christ. “If any man come after me, let him deny himself, take up his cross, and follow me.” Matthew 16:24.
