Philippians 2:5–11 (NASB95) 5 Have this attitude in yourselves which was also in Christ Jesus, 6 who, although He existed in the form of God, did not regard equality with God a thing to be grasped, 7 but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. 8 Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross. 9 For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name, 10 so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth, 11 and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father. "He existed in the form of God..." in the Greek "morphe theos huparchon" meaning he never ceased to be God. And he did not regard his own equality with God (the Father and the Holy Spirit) a thing to brandish or prized, or lorded over anyone but emphasized his extreme humility in taking upon himself the additional nature of a human slave... to God. When did the sacrifice and suffering of Christ begin? Right here.
