Philippians 2:5-7
Your attitude should be the same as that of Christ Jesus:
Who, being in very nature God, did not consider equality with God to be robbery,
but made himself nothing, taking the very nature of a servant,
being made in human likeness.
Jesus very nature was that of God, he was God. But he was a man in manifestation.
Everything he did on the earth during his life here was done as a man. All the miracles, the healing, the seeing into the hearts of men... all was done as a man anointed of the Father. One purpose of God become man in Jesus is to reconcile all mankind to God, to bring all things under Jesus as a man, and Jesus as a man being already completely submitted to God the Father means that all creation will be submitted to God when all creation is submitted to Christ Jesus as a man.
John 1:1-3 KJV
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made.
Jesus was and is the Word, and he was and is God, all things were made by Jesus.
Colossians 1:15-20
He is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. For God was pleased to have all his fullness dwell in him, and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
All things were created in Jesus, who was before all things and who is the Head of his Body, the Church (us). He was 1st born from the dead so that in all things he has supremacy over us all, he is the Head, and our Lord. Through Jesus all things in heaven and in earth will be completely reconciled to God the Father.
