Philemon 1:12-16

He is my very heart, and I’ve sent him back to you with this letter. I would have preferred to keep him at my side so that he could take your place as my helper during my imprisonment for the sake of the gospel. However, I did not want to make this decision without your consent, so that your act of kindness would not be a matter of obligation but out of willingness. Perhaps you could think of it this way: he was separated from you for a short time so that you could have him back forever. So welcome him no longer as a slave, but more than that, as a dearly loved brother. He is that to me especially, and how much more so to you, both humanly speaking and in the Lord.
