Philippians 2:3-8

Do nothing from selfishness or empty conceit, but with humility consider one another as more important than yourselves; do not merely look out for your own personal interests, but also for the interests of others. Have this attitude in yourselves which was also in Christ Jesus, who, as He already existed in the form of God, did not consider equality with God something to be grasped, but emptied Himself by taking the form of a bond-servant and being born in the likeness of men. And being found in appearance as a man, He humbled Himself by becoming obedient to the point of death: death on a cross.
