Philippians 2:1-4 (NASB)
1  Therefore if there is any encouragement in Christ, if there is any consolation of love, if there is any fellowship of the Spirit, if any  affection and compassion,  2  make my joy complete by being of the same mind, maintaining the same love, united in spirit, intent on one purpose.  3  Do nothing from  selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves;  4  do not merely look out for your own personal interests, but also for the interests of others.
