Why Worship an Empty God? (Philippians 2:5-8)

The Lord is one who has every right to demand that we live as a servant people counting one another as better than ourselves. We should do this because we are the Lord’s people. However, if we are honest, the motivation of just saying, “Well, God demands it,” does not always motivate us to conform to the Lord. Is there another reason we should want to live as slave people for the Lord? If there is another reason then what is that reason?
