Summary: Paul continues by exhorting them to have the same love, doing nothing out of vain conceit, giving the example of Christ Jesus, who emptied himself to take the form of a servant in the likeness of men and obedient unto death of the cross. He explains that it is God who works in them and that in obeying they will be seen as lights in the world. He knows they have been worried about Epaphroditus, who was sick nearly to the point of death, so he is sending him back to them. Read from the World English Bible.
