Through his power all things were made--things in heaven and on earth, things seen and not seen, all {spiritual} powers, authorities, lords, and rulers. All things were made through Christ and for Christ.
Christ is the head of the body. (The body is the church.) Everything comes from him. And he is the Lord F5 who was raised from death. So in all things Jesus is most important.
And through Christ, God was happy to bring all things back to himself again--things on earth and things in heaven. God made peace by using Christ's blood (death) on the cross.
