Colossians 2:10-11 And you are complete in him, which is the head of all principality and power: In whom also you are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ
‘Complete in him’ – we need nothing more when we are in Him [in unity] (John 15:1-7). The so-called doctrine of interpenetration, that is, persons entering physical into each other, is false. The Bible does speak of the Corinthians and Philippians being in Paul’s heart (2Cor. 7:3; Php. 1:7); God being in Christ (2Cor. 5:19); Christ being in God (John 14:20); God and Christ being in each other (John 14:10-11); men being in both the Father and the Son (1Jn. 2:24); men being in Christ (2Cor. 5:17); men and the Spirit being in each other (Rom. 8:9); Christ being in men (Col. 1:27; Rom. 8:10); man and Christ being in each other (John 14:20); all creation being in God (Acts 17:28); and satan entering into men (Luke 22:3; John 13:27). However, these passages refer to being in union with, being consecrated to the same end – one in mind, purpose, and life. They do not teach the physical entrance of one being into another. It may be best understood by a man and woman becoming one in life together, being in each other’s plans, life, etc.
‘In whom also you are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ.’ Literally, in Him, you have been circumcised, not by cutting the flesh, but by the circumcision of Christ in putting off the body of sins of the flesh. Christ became circumcised and fulfilled all the Law to become a true mediator between God and man. Now through Him, we are freed from all Mosaic law observance and have been redeemed through the work of Christ on the cross (2:11-17; 1:14, 20-25; 1Pet. 2:24).
