"We see here the care the apostle takes to prevent their being offended at his sufferings. He was now a prisoner at Rome; this might be a stumbling-block to those who had received the gospel by his ministry. They might be tempted to think, If this doctrine were indeed of God, God would not suffer one who was so active and instrumental in preaching and propagating it to be thrown by as a despised broken vessel. They might be shy of owning this doctrine, lest they should be involved in the same trouble themselves. Now to take off the offence of the cross, he expounds this dark and hard chapter of his sufferings, and makes it very easy and intelligible, and reconcilable to the wisdom and goodness of God who employed him."With that in mind, we can see why Paul is contemplating his death,
"For to me, living is Christ and dying is gain. If I am to live in the flesh, that means fruitful labour for me; and I do not know which I prefer. I am hard pressed between the two: my desire is to depart and be with Christ, for that is far better; but to remain in the flesh is more necessary for you. Since I am convinced of this, I know that I will remain and continue with all of you for your progress and joy in faith, so that I may share abundantly in your boasting in Christ Jesus when I come to you again."
"Only, live your life in a manner worthy of the gospel of Christ, so that, whether I come and see you or am absent and hear about you, I will know that you are standing firm in one spirit, striving side by side with one mind for the faith of the gospel, and are in no way intimidated by your opponents. For them this is evidence of their destruction, but of your salvation. And this is God’s doing. For he has graciously granted you the privilege not only of believing in Christ, but of suffering for him as well— since you are having the same struggle that you saw I had and now hear that I still have."
The cure for the jailhouse blues, even maybe the death row blues may be just this, to stay alive for Christ and for others for the labour is never done.
