Why does Christ have pre-eminence in all things?
By Christ all things were created and are held together; He is before all things, He is Head of the Body, the Church, the beginning, the firstborn from the dead, and it pleased the Father that all fullness should dwell in Him.
Les explains from Colossians 1, beginning at verse 15, that God the Son is the image of the invisible God and the firstborn of every creature, meaning Christ was pre-eternal in His existence just like God the Father and God the Spirit. By Him all things were created in heaven and earth, visible and invisible, including thrones and dominions, and He is before all things; by Him all things consist, or are held together. He is also the Head of the Body, the Church, the beginning, the firstborn from the dead, referring to His resurrection. The purpose is that in all things He might have the pre-eminence, for it pleased the Father that in Christ all fullness should dwell. Les notes the members of the Godhead are not one above another; they are co-equal.
