Having confidence in thy obedience - That you would comply with all my expressed desires.

I wrote unto thee - "I have written to you;" to wit, in this Epistle.

Knowing that thou wilt also do more than I say - In all the respects which he had mentioned - in receiving Onesimus, and in his kind treatment of him. He had asked a great favor of him, but he knew that he would go even beyond what he had asked.

Having confidence in thy obedience - I know that it will please thee thus to oblige thy friend, and I know that thou wilt do more than I request, because thou feelest the affection of a son to thy spiritual father. Some think that the apostle hints to Philemon that he should manumit Onesimus.

Having confidence in thy obedience,.... In his obedience of faith to Christ, and his Gospel; he having been made willing in the day of his power to serve him, as well as to be saved by him; and being constrained by his love, and the Spirit of Christ having wrought in him both to will and to do of his good pleasure:

l wrote unto thee, knowing that thou wilt also do more than I say; the knowledge the apostle had of Philemon's cheerful obedience to Christ in all the parts of duty, encouraged him to write to him, on this head; believing that he would even do more than he had desired of him.

More than I say (ὑπέρ)

Beyond. Possibly hinting at manumission.

Having confidence in thy obedience I wrote unto thee, knowing that thou wilt also do more than I say.

1:21 Having confidence... that thou wilt also do more than I say. This letter is written in full confidence that even more than I ask will be granted. Perhaps this is a hint that Philemon might grant Onesimus his freedom.

21. Having confidence in thy obedience-to my apostolic authority, if I were to "enjoin" it (Phm 8), which I do not, preferring to beseech thee for it as a favor (Phm 9).

thou will also do more-towards Onesimus: hinting at his possible manumission by Philemon, besides, being kindly received.

1:15-22 When we speak of the nature of any sin or offence against God, the evil of it is not to be lessened; but in a penitent sinner, as God covers it, so must we. Such changed characters often become a blessing to all among whom they reside. Christianity does not do away our duties to others, but directs to the right doing of them. True penitents will be open in owning their faults, as doubtless Onesimus had been to Paul, upon his being awakened and brought to repentance; especially in cases of injury done to others. The communion of saints does not destroy distinction of property. This passage is an instance of that being imputed to one, which is contracted by another; and of one becoming answerable for another, by a voluntary engagement, that he might be freed from the punishment due to his crimes, according to the doctrine that Christ of his own will bore the punishment of our sins, that we might receive the reward of his righteousness. Philemon was Paul's son in the faith, yet he entreated him as a brother. Onesimus was a poor slave, yet Paul besought for him as if seeking some great thing for himself. Christians should do what may give joy to the hearts of one another. From the world they expect trouble; they should find comfort and joy in one another. When any of our mercies are taken away, our trust and hope must be in God. We must diligently use the means, and if no other should be at hand, abound in prayer. Yet, though prayer prevails, it does not merit the things obtained. And if Christians do not meet on earth, still the grace of the Lord Jesus will be with their spirits, and they will soon meet before the throne to join for ever in admiring the riches of redeeming love. The example of Onesimus may encourage the vilest sinners to return to God, but it is shamefully prevented, if any are made bold thereby to persist in evil courses. Are not many taken away in their sins, while others become more hardened? Resist not present convictions, lest they return no more.
