Philemon 1:8-10

Therefore [on the basis of these facts], though I have enough confidence in Christ to order you to do what is appropriate, yet for love’s sake I prefer to appeal to you—since I am such a person as Paul, an old man, and now also a prisoner [for the sake] of Christ Jesus— I appeal to you for my [own spiritual] child Onesimus, whom I have fathered [in the faith] while a captive in these chains.
