When Paul says that Jesus laid aside His divinity, or did not think equality with God something to be grasped... why would you assume it means that He was not divine while on earth? How could He be fully Human AND fully Divine then? Why don't you consider  it to mean that He did not FLAUNT Himself or make Himself known publicly as God? And yet, He did raise the dead, give sight to the blind, etc....... no mere mortal can do that.
