Paul appreciated the Philippians greatly. Here in this text is the caveat he expressed. His great appreciation was contingent “only” with their continued “conduct” being “worthy of the gospel of Christ.”
There needed to be unity, standing fast “in one spirit, with one mind.” There needed to be effort, “striving together” for the gospel. There needed to be courage in the face of their opponents, here probably referring to non-Christian Gentiles, as Philippi was a Roman city.
Consider of what these things were proof. First that the Christian’s lack of fear showed their understanding that God was with them. It would indicate to the pagans surrounding them that perdition (ruin) followed those who opposed God, but that salvation from the one true God would be granted to the brethren in Philippi. Great conviction creates doubt in the mind of the enemy!
Yes, we will suffer, but in the end is glory! (cf. Matthew 10:28).
