Christ was already equal with God, possessing all of the same Divine attributes possessed by God the Father. It would be no “robbery, ” therefore, if He came into the world and demanded all men immediately serve Him and worship Him as God. But in fact He came more “quietly” into this world. He made Himself of no reputation and became as it were a servant (verse 7). He left us an example of humility that we ought to emulate.
And we pray:
Lord Jesus, You didn’t come into the world to be served but to serve and to give Your life as a ransom for Mankind. Help us to learn true humility from Your example left to us in Scripture. You always submitted to The Father, even to the point of enduring the pain and agony of the cross. Help us to endure all things with joy that God has made our lot to bear, knowing that it will turn to our benefit in the end. Amen.
