Philippians 1:27-30 New Revised Standard Version (NRSV)
27 Only, live your life in a manner worthy of the gospel of Christ, so that, whether I come and see you or am absent and hear about you, I will know that you are standing firm in one spirit, striving side by side with one mind for the faith of the gospel, 28 and are in no way intimidated by your opponents. For them this is evidence of their destruction, but of your salvation. And this is God’s doing. 29 For he has graciously granted you the privilege not only of believing in Christ, but of suffering for him as well— 30 since you are having the same struggle that you saw I had and now hear that I still have.
