Passage
that the fellowship of thy faith may become working in the full knowledge of every good thing that <FI>is<Fi> in you toward Christ Jesus;
that the fellowship of thy faith may become working in the full knowledge of every good thing that <FI>is<Fi> in you toward Christ Jesus;
Philemon 1:4 I give thanks to my God, always making mention of thee in my prayers,
Philemon 1:5 hearing of thy love and faith that thou hast unto the Lord Jesus and toward all the saints,
Philemon 1:6 that the fellowship of thy faith may become working in the full knowledge of every good thing that <FI>is<Fi> in you toward Christ Jesus;
Philemon 1:7 for we have much joy and comfort in thy love, because the bowels of the saints have been refreshed through thee, brother.
Philemon 1:8 Wherefore, having in Christ much boldness to command thee that which is fit--
The verse centers on "faith", "fellowship", "become", "working", "full", "knowledge", "good", and "toward". It is saying that the verse draws attention to "faith" and "fellowship", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "hearing of thy love and faith that..." into verse 7's "for we have much joy and comfort...", so "faith" and "fellowship" 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 "faith" and "fellowship" with trust shaped by these words, not by a vague optimism outside the passage.
