So then death worketh in us - We are exposed to death. The preaching of the gospel exposes us to trials which may be regarded as death working in us. Death has an energy over us (ἐνεργεῖται energeitai, is at work, is active, or operates); it is constantly employed in inflicting pains on us, and subjecting us to privation and trials. This is a strong and emphatic mode of saying that they were always exposed to death. We are called to serve and glorify the Redeemer, as it were, by repeated deaths and by constantly dying.

But life in you - You live as the effect of our being constantly exposed to death. You reap the advantage of all our exposure to trials, and of all our sufferings. You are comparatively safe; are freed from this exposure to death; and will receive eternal life as the fruit of our toils, and exposures. Life here may refer either to exemption from danger and death; or it may refer to the life of religion; the hopes of piety; the prospect of eternal salvation. To me it seems most probable that Paul means to use it in the latter sense, and that he designs to say that while he was exposed to death and called to endure constant trial, the effect would be that they would obtain, in consequence of his sufferings, the blessedness of eternal life; compare 2 Corinthians 4:15. Thus understood, this passage means, that the sufferings and self-denials of the apostles were for the good of others, and would result in their benefit and salvation; and the design of Paul here is to remind them of his sufferings in their behalf, in order to conciliate their favor and bind them more closely to him by the remembrance of his sufferings on their account.

Death worketh in us, etc. - We apostles are in continual danger, and live a dying life; while you who have received this Gospel from us are in no danger.

So then death worketh in us,.... This is the conclusion of the foregoing account, or the inference deduced from it; either the death, or dying of Christ, that is, the sufferings of his body, the church, for his sake, "is wrought in us"; fulfilled and perfected in us; see Colossians 1:24 or rather a corporeal death has seized upon us; the seeds of death are in us; our flesh, our bodies are mortal, dying off apace; death has already attacked us, is working on our constitutions gradually, and unpinning our tabernacles, which in a short time will be wholly took down and laid in the dust:

but life in you. Some understand these words as spoken ironically, like those in 1 Corinthians 4:8 but the apostle seems not to be speaking in such a strain, but in the most serious manner, and about things solemn and awful; and his meaning is, ours is the sorrow, the trouble, the affliction, and death itself, yours is the gain, the joy, the pleasure, and life; what we get by preaching the Gospel are reproach, persecution, and death; but this Gospel we preach at such expense is the savour of life unto life to you, and is the means of maintaining spiritual life in your souls, and of nourishing you up unto eternal life; and which is no small encouragement to us to go on in our work with boldness and cheerfulness: or these words regard the different state and condition of the apostle, and other ministers, and of the Corinthians; the one were in adversity, and the other in prosperity.

{7} So then death worketh in us, but life in you.

(7) A very wise conclusion: as if he would say, Therefore, to be short, we die that you may live by our death, because they ventured into all those dangers for the building of the Church's sake, and they ceased not to strengthen and encourage all the faithful with the examples of their patience.

4:12 So then death worketh in us, but life in you. The ever present image of death, threatening the gospel ministers, was the means of life to the saved.

4:12 So then death worketh in us, but life in you - You live in peace; we die daily. Yet - Living or dying, so long as we believe, we cannot but speak.

12. The "death" of Christ manifested in the continual "perishing of our outward man" (2Co 4:16), works peculiarly in us, and is the means of working spiritual "life" in you. The life whereof we witness in our bodily dying, extends beyond ourselves, and is brought by our very dying to you.

4:8-12 The apostles were great sufferers, yet they met with wonderful support. Believers may be forsaken of their friends, as well as persecuted by enemies; but their God will never leave them nor forsake them. There may be fears within, as well as fightings without; yet we are not destroyed. The apostle speaks of their sufferings as a counterpart of the sufferings of Christ, that people might see the power of Christ's resurrection, and of grace in and from the living Jesus. In comparison with them, other Christians were, even at that time, in prosperous circumstances.
