Philemon 1:8-12

Therefore, although in Christ I could be bold and order you to do what you ought to do, yet I prefer to appeal to you on the basis of love. It is as none other than Paul—an old man and now also a prisoner of Christ Jesus— that I appeal to you for my son Onesimus, who became my son while I was in chains. Formerly he was useless to you, but now he has become useful both to you and to me. I am sending him—who is my very heart—back to you.
