Philippians 2:2-4

make my joy complete by being of the same mind, having the same love [toward one another], knit together in spirit, intent on one purpose [and living a life that reflects your faith and spreads the gospel—the good news regarding salvation through faith in Christ]. Do nothing from selfishness or empty conceit [through factional motives, or strife], but with [an attitude of] humility [being neither arrogant nor self-righteous], regard others as more important than yourselves. Do not merely look out for your own personal interests, but also for the interests of others.
