Concept:Paul intercedes for a runaway slave named Onesimus and asks Philemon to forgive him.

Onesimus, his slave, ran away and later met Paul while Paul was in prison.
Through Paul's teaching, Onesimus became a believer in Christ.

He urged Philemon to forgive Onesimus and receive him warmly.
Paul even offered to repay any debt or wrong Onesimus had caused.
This request shows Christian forgiveness and reconciliation between master and servant.
