11 Therefore remember that you, once Gentiles in the flesh—who are called Uncircumcision by what is called the Circumcision made in the flesh by hands—12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. (Ephesians 2:11–13, NKJV)
The fleshly circumcision that identified Israel as God’s covenant people was an operation performed “in the flesh by hands” (v. 11). Removing the foreskin was a foreshadowing of the “circumcision of Christ,” which is “the putting off of the body of the sins of flesh” – the operation God performs when a sinner is “buried with Him (Christ, jrp) in baptism” (Colossians 2:11-12). Baptism is an action of faith in the power of God that saves the sinner and raises him or her to spiritual life in Christ (Colossians 2:12). Whether you are a Jew or Gentile in the flesh does not matter. In this gospel age, one is not a child of God until the circumcision of Christ occurs in the heart, as the sinner is buried with Christ in baptism and God forgives his or her sins by the blood of Christ (Colossians 2:13). That is when the sinner rises from spiritual death to walk in newness of life.
