Philippians 1:27-28

Whatever happens, conduct yourselves in a manner worthy of the gospel of Christ. Then, whether I come and see you or only hear about you in my absence, I will know that you stand firm in the one Spirit, striving together as one for the faith of the gospel without being frightened in any way by those who oppose you. This is a sign to them that they will be destroyed, but that you will be saved—and that by God.
