“For in Him dwells all the fullness of the Godhead bodily; and you are complete in Him, who is the head of all principality and power.” (Colossians 2:9-10 NKJV).

Christ Jesus is “all” God and “all” man. This is a paradox, yet precisely what the Bible reveals. As the second person of the “Godhead,” which is the Trinity, He was, and is, absolute and perfect God. All the “fullness” of the essence of God is in Him “bodily.” As the apostle John wrote, “The Word became flesh” (John 1:14). Jesus is God in the flesh. When we receive Christ as Savior and Lord, He is the “Head” and we are members of His body. Having received Christ, we are “complete in Him.” There is nothing missing, nothing to be added. So, the apostle Paul argued against the Judaizers, who would require Gentile believers to be circumcised and follow Jewish laws, on this basis. In Christ, believers are “complete.” They are already “circumcised with the circumcision made without hands” (Col. 2:11) because they have been made “complete in Him.”
Dearly beloved, you are complete in Christ!
