Philemon 1:15

1:15 For perhaps it was for this reason that he was separated from you for a little while, so that you would have him back eternally,

sn So that you would have him back eternally. The notion here is not that Onesimus was to be the slave of Philemon eternally, but that their new relationship as brothers in Christ would transcend the societal structures of this age. The occasion of Onesimus’ flight to Rome would ultimately be a catalyst in the formation of a new and stronger bond between these two men.
