Though Jesus was in every way God, He took off His royal coat, put it aside and took a form of a servant.
Only those who are like children can take a form of a servant. For when you become a child, God is able to [fully] perform in your life. God wants to find Himself alone with us in order to work as He pleases. He is looking for [those with the spirit of a] child to tell forth of His strength without interference.
