Passage
whom I did send again, and thou him (that is, my own bowels) receive,
whom I did send again, and thou him (that is, my own bowels) receive,
Philemon 1:10 I entreat thee concerning my child--whom I did beget in my bonds--Onesimus,
Philemon 1:11 who once was to thee unprofitable, and now is profitable to me and to thee,
Philemon 1:12 whom I did send again, and thou him (that is, my own bowels) receive,
Philemon 1:13 whom I did wish to retain to myself, that in thy behalf he might minister to me in the bonds of the good news,
Philemon 1:14 and apart from thy mind I willed to do nothing, that as of necessity thy good deed may not be, but of willingness,
The verse centers on "send", "again", "thou", "bowels", and "receive". It is saying that the verse draws attention to "send" and "again", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "who once was to thee unprofitable and..." into verse 13's "whom I did wish to retain to...", so "send" and "again" belong inside that flow. In Philemon context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "send" and "again" with trust shaped by these words, not by a vague optimism outside the passage.
