Philippians 2:5-6, 8, 10-11

Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped

And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.

so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
