Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others.

In your relationships with one another, have the same mindset as Christ Jesus:

Who, being in very nature God,    did not consider equality with God something to be used to his own advantage;rather, he made himself nothing    by taking the very nature of a servant,    being made in human likeness.And being found in appearance as a man,    he humbled himself    by becoming obedient to death—        even death on a cross!

Philippians 2:3-8
