Today we learned about a story of Onesimus,Philemon,Paul. Onesimus stole form Philemon and Ran away to Rome.There he met paul.Paul wrote a letter to Philemon on behalf of Onesimus. Onesimus Retured back to Clossae and said Sorry. I think it is not easy to say sorry......Because he stole People can say.....Forgive me
