Paul’s letter to Philemon had a specific purpose. He wanted to appeal to Philemon to receive his slave, Onesimus, back as a brother. He had apparently fled and fell into the hands of Paul who converted him. He was now profitable to both Philemon and Paul (v. 11).
In preparation for his appeal to Philemon, Paul showed his appreciation for him. It is obvious that Paul had a history with this brother due to his greeting, “Paul, a prisoner of Christ Jesus” as opposed to his usual greeting, “Paul an apostle.” Philemon already knew of the authority of Paul’s apostleship. Paul wanted to “appeal” to him rather than “command [him] what was fitting.” Paul consistently prayed for Philemon. He heard, perhaps from Onesimus, of his “love and faith which [he had] toward the Lord Jesus and toward all the saints.” Tactfully, Paul mentioned Philemon’s good works in the “sharing of [his] faith.” His later appeal for Philemon would be to continue with those good works by receiving Onesimus. Philemon was rightly commended by Paul. This was not an attempt to flatter him, but a recognition and reminder of the need for continual love toward the saints. Paul’s tone toward Philemon is one that should be emulated throughout the brotherhood.
It is important to note that our actions, whether good or bad, are recognized by other saints. Our actions can either be refreshing, or discouraging. When we continue in good works we have a positive effect on each other. We can experience joy, comfort, and refreshment by our obedience to Christ, and love for one another.
