Philippians 2:6-8

⁶who, although He existed in the form of God, did not regard equality with God a thing to be grasped, ⁷but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. ⁸Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.
