Philippians 2:2-4

2:2 complete my joy and be of the same mind, by having the same love, being united in spirit, and having one purpose. 2:3 Instead of being motivated by selfish ambition or vanity, each of you should, in humility, be moved to treat one another as more important than yourself. 2:4 Each of you should be concerned not only about your own interests, but about the interests of others as well.
