Christ gave up His riches and heavenly glory to be born in a manger. He gave up His independent exercise of authority to submit to the greater will of the Father to accomplish redemption on earth. Christ gave all of that up so that we could have a right relationship with Him and with one another. He gave all of that up so that we could be our highest and best selves, re-created selves, and redeemed selves. He emptied Himself so that we could be full of Him.
