Can it be out of the kindness of my heart that I carry out such a labor of mercy on a people who once captured me when they wrecked my father's house and carried off his servants? For by descent I was a freeman, born of a decurion father; yet I have sold this nobility of mine, I am not ashamed, nor do I regret that it might have meant some advantage to others. In short, I am a slave in Christ to this faraway people for the indescribable glory of "everlasting life which is in Jesus Christ our Lord."
