Only let your conduct be worthy of the gospel of Christ.

being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ; just as it is right for me to think this of you all, because I have you in my heart, inasmuch as both in my chains and in the defense and confirmation of the gospel, you all are partakers with me of grace. For God is my witness, how greatly I long for you all with the affection of Jesus Christ. And this I pray, that your love may abound still more and more in knowledge and all discernment, that you may approve the things that are excellent, that you may be sincere and without offense till the day of Christ, being filled with the fruits of righteousness which are by Jesus Christ, to the glory and praise of God. Some indeed preach Christ even from envy and strife, and some also from goodwill: The former preach Christ from selfish ambition, not sincerely, supposing to add affliction to my chains; but the latter out of love, knowing that I am appointed for the defense of the gospel. What then? Only that in every way, whether in pretense or in truth, Christ is preached; and in this I rejoice, yes, and will rejoice. Only let your conduct be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of your affairs, that you stand fast in one spirit, with one mind striving together for the faith of the gospel, and not in any way terrified by your adversaries, which is to them a proof of perdition, but to you of salvation, and that from God. For to you it has been granted on behalf of Christ, not only to believe in Him, but also to suffer for His sake, having the same conflict which you saw in me and now hear is in me.  Philippians 1:6-11,15-18,27-30 - NKJV
