4 The name Philemon means "fond". He seems to have been a most exemplary character, whose reputation had reached Paul's ears, and had given him joy in the midst of the sorrows and dangers of his situation in Rome. But Paul is not thinking of himself but of the service Philemon renders to the saints.
8 Paul's apostolic authority gives him the right to dictate to Philemon regarding Onesimus. It would have been perfectly proper to have held the run away slave for his own comfort and service without consulting his master in the matter. Yet grace does not demand its rights, or stand upon its privileges, but, led by love, entreats. What a glorious sunset to such a life as Paul's! The rare graces of the gospel glow in the aged apostle and prisoner with greater splendor than ever before. Age has not soured but rather mellowed him.
11 There is a pleasing play upon the name "Onesimus", which means profitable. Paul uses it as a verb in verse twenty. He may be regarded as a picture of those of the nations who had strayed away from God, who are the fruit of Paul's bonds as Onesimus was, and who now return to God to become His "profitable" slaves. He is also a marvelous example of God's method of tranforming evil into good. No one would condone the act of Onesimus in running away from his master, yet God made it a blessing not only to Onesimus, but to his master and to Paul. All were enriched by it.
In this way He is able to make all evil subserve His purpose. It is the background of His grace and will become the means of drawing His creatures infinitely closer to Himself and His affections than would be possible if sin had never invaded the universe.
15 The short period of Onesimus' absence was not worth reckoning compared with the fact that, as a brother in Christ, Philemon would have him for all the eons. So the short term of sin (which seems to us so long) is not worth reckoning compared with the eonian and everlasting tenure of the bliss which follows it.
15 Collect as a repayment, from-have, is a special term used in the papyri for receiving in full for any debt or obligation. Thus the Lord, in the sixth of Matthew, said concerning those whose deeds were done before men, that "they are collecting their wages," i.e. they have their reward and the receipt for it in full—there is no more due them from God.
18 Philemon was evidently called under Paul's preaching, so that he owed all he had in grace to his ministry. With all this to his credit, Paul may well assume all of Onesimus' debts to his master.
20 There is a play on the name Onesimus, or Profitable. If he should be sent back to Paul, to serve him in the evangel, he would indeed be "Profitable" to Paul, both in name and in fact.
22 At this time Paul still hoped to be released and return to his itinerant ministry. But the very spiritual character of his latest ministry did not demand his physical presence. It was more in keeping to convey it by epistles. We have no evidence to show that he ever went to Colosse.
23 Later, all except Luke left him (2Ti .4:1l ). Demas abandoned him. And to this very day his inspired epistles, by means of which he still speaks, and which are the only source of the truth for this economy of God's grace, are often unheeded, neglected, abandoned, forsaken.
