Philippians 2:5–7
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, but emptied himself, by taking the form of a servant, being born in the likeness of men.
Paul is not saying that Christ became less than God or “gave up” some divine attributes; he is not even commenting directly on the question of whether Jesus was fully omnipotent or omniscient during his time on earth. Nor is he saying that Christ ever gave up being “in the form of God.” Rather, Paul is stressing that Christ, who had all the privileges that were rightly his as king of the universe, gave them up to become an ordinary Jewish baby bound for the cross. Christ “emptied himself” by taking the form of a servant, being born in the likeness of men (roughly equivalent phrases). While he had every right to stay comfortably where he was, in a position of power, his love drove him to a position of weakness for the sake of sinful mankind
