To become like Christ, we must first recognize that he was God who became like us so we might become like him. He was Lord and became a servant so we might become friends. He was rich and became poor so that we could become rich. He came down so that we might be exalted.
Therefore, to become like Christ is acknowledge that in him we have first received the reality of sharing in his divine nature, the mantle of his authority, and his great riches. It is then from this exalted position in Christ we humble ourselves to lift up others. He became like us so we might become like him.
