Philippians 4:1

Textus Receptus:
ωστε αδελφοι μου αγαπητοι και επιποθητοι χαρα και στεφανος μου ουτως στηκετε εν κυριω αγαπητοι

King James:
Therefore, my brethren dearly beloved and longed for, my joy and crown, so stand fast in the Lord, my dearly beloved.

Comments:
dearly beloved... dearly beloved: Paul uses the same word in chapter 2:12 where he also gives them an edict regarding their behavior. He is not simply sugar-coating medicine. He is grounding obedience the same way the Lord does in passages like John 15:12.

stand fast: The same word in chapter 1:27 describes what Paul hopes to find the Philippians doing when (and if) he visits them, and it is used in the same context of unity.

Expanded Paraphrase:
Since Christ is transforming you and your only enemies are the enemies of the cross, as I count you my brothers in Christ, loving and missing you, regarding you fondly and realizing my own victory in your obedience, so persevere in Christ, allowing your love for Him to be revealed in how you treat each other, just as I love you.
