So you also are complete through your union with Christ, who is the head over every ruler and authority.
When you came to Christ, you were “circumcised,” but not by a physical procedure. Christ performed a spiritual circumcision—the cutting away of your sinful nature.
References for Colossians 2:11
For you were buried with Christ when you were baptized. And with him you were raised to new life because you trusted the mighty power of God, who raised Christ from the dead.
You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins.
He canceled the record of the charges against us and took it away by nailing it to the cross.
In this way, he disarmed the spiritual rulers and authorities. He shamed them publicly by his victory over them on the cross.
