Passage
If then thou countest me a partner, receive him as myself.
If then thou countest me a partner, receive him as myself.
Philemon 1:15 For perhaps he was therefore parted [from thee] for a season, that thou shouldest have him for ever;
Philemon 1:16 no longer as a servant, but more than a servant, a brother beloved, specially to me, but how much rather to thee, both in the flesh and in the Lord.
Philemon 1:17 If then thou countest me a partner, receive him as myself.
Philemon 1:18 But if he hath wronged the at all, or oweth [thee] aught, put that to mine account;
Philemon 1:19 I Paul write it with mine own hand, I will repay it: that I say not unto thee that thou owest to me even thine own self besides.
The verse centers on "thou", "countest", "partner", "receive", and "myself". It is saying that the verse draws attention to "thou" and "countest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "no longer as a servant but more..." into verse 18's "But if he hath wronged the at...", so "thou" and "countest" 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 "thou" and "countest" with trust shaped by these words, not by a vague optimism outside the passage.
