Do nothing out of rivalry or conceit but in humility consider others as more important than yourselves. Everyone should look out not only for his own interests, but also for the interests of others.
Philippians 2:3-4 HCSB
Rivalry and conceit are, indeed, prime motivating factors in competition as we know it in the American free market economy. Our human nature is to look out for ourselves first and foremost, but God tells us to stop and look beyond ourselves to the needs and interests of others. In God’s economy there is no place for rivalry next to unity, striving next to peace, jealousy next to contentedness.
Unity in Christ comes when we place others before ourselves for the cause of Christ. 🚦
