Have this mind among yourselves, which is yours in Christ Jesus, ⁶ who, though he was in the form of God, did not count equality with God a thing to be grasped, ⁷ but emptied himself, by taking the form of a servant, being born in the likeness of men. ⁸ And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.

 

(Philippians 2:5-8 -- ESV)
