Conduct Becoming a Christian

Philippians 1:27-30

27 Only conduct yourselves in a manner worthy of the gospel of Christ, so that whether I come and see you or remain absent, I will hear of you that you are standing firm in one spirit, with one mind striving together for the faith of the gospel; 28 in no way alarmed by your opponents — which is a sign of destruction for them, but of salvation for you, and that too, from God. 29 For to you it has been granted for Christ’s sake, not only to believe in Him, but also to suffer for His sake, 30 experiencing the same conflict which you saw in me, and now hear to be in me.
NASU

Action: How am I to conduct myself in all circumstances?
