Albert Barnes Commentary Philippians 2:21

"For they all seek their own, not the things of Jesus Christ." — Philippians 2:21 (ASV)

For all seek their own. That is, all who are with me. Who Paul had with him at this time is not fully known, but he doubtless means that this remark should apply to the mass of Christians and Christian ministers then in Rome. Perhaps he had proposed to some of them to go and visit the church at Philippi, and they had declined it because of the distance and the dangers of the way.

When the trial of Paul came on before the emperor, all who were with him in Rome fled from him (2 Timothy 4:16); and it is possible that the same disregard of his wishes and his welfare had already begun to manifest itself among the Christians who were at Rome, so that he was constrained to say that, as a general thing, they sought their own ease and comfort, and were unwilling to deny themselves in order to promote the happiness of those who lived in the remote parts of the world.

Let us not be harsh in judging them. How many professing Christians in our cities and towns are there now who would be willing to leave their business and their comfortable homes, and go on an embassy like this to Philippi? How many are there who would not seek some excuse, and show that it was a characteristic that they "sought their own" rather than the things which pertained to the kingdom of Jesus Christ?

Not the things which are Jesus Christ's. Which pertain to his cause and kingdom. They are not willing to practice self-denial in order to promote that cause. It is implied here:

1. that it is the duty of those who profess religion to seek the things which pertain to the kingdom of the Redeemer, or to make that the great and leading object of their lives. They are bound to be willing to sacrifice "their own" things—to deny themselves of ease, and to be always ready to expose themselves to peril and want if they may be the means of advancing his cause.
2. That frequently this is not done by those who profess religion. It was the case with the professed Christians at Rome, and it is often the case in the churches now. There are few Christians who deny themselves much to promote the kingdom of the Redeemer; few who are willing to lay aside what they regard as "their own" in order to advance his cause. Men live for their own ease; for their families; for the prosecution of their own business—as if a Christian could have anything which he has a right to pursue independently of the kingdom of the Redeemer, and without regard to his will and glory.
