If you have any encouragement from being united with Christ, if any comfort from His love, if any fellowship with the Spirit, if any tenderness and compassion, then make my joy complete by being like-minded, having the same love, being one in spirit and purpose.  Do nothing out of selfish ambition or vain conceit, but in humility consider others better then yourselves.  Each of you should look not only to your own interest, but also to the interest of others. 
Philippians 2:1-4
