WAEC Christian Religious Studies 2003 Theory question 111

Onesimus, Philemon's slave, had run away and possibly wronged his master (Philemon 15, 18).
He met Paul in prison and became a Christian: "my child… whose father I have become in my imprisonment" (Philemon 10).
Once useless, he had become useful (Philemon 11).
Paul sent him back, appealing to Philemon on the basis of love rather than command (Philemon 8-9, 12).
He suggested God allowed the separation so that Philemon might have him back for ever (Philemon 15).
Philemon should receive him no longer as a slave but as a beloved brother (Philemon 16).
"Receive him as you would receive me" (Philemon 17).
Paul offered to repay any wrong or debt: "charge that to my account" (Philemon 18-19).
He was confident Philemon would do even more than he asked (Philemon 21).
Thus forgiveness means receiving the repentant offender back fully, restoring the relationship, cancelling the debt, and treating him as an equal in Christ, as Christ forgave us.

Explain the steps of Paul's appeal and what they teach about forgiveness.
