Philippians 1:27-28

27Only [be sure to] lead your lives in a manner [that will be] worthy of the gospel of Christ, so that whether I do come and see you or remain absent, I will hear about you that you are standing firm in one spirit [and one purpose], with one mind striving side by side [as if in combat] for the faith of the gospel.

28And in no way be alarmed or intimidated [in anything] by your opponents, for such [constancy and fearlessness on your part] is a [clear] sign [a proof and a seal] for them of [their impending] destruction, but [a clear sign] for you of deliverance and salvation, and that too, from God.
