Passage
hearing of thy love and the faith which thou hast towards the Lord Jesus, and towards all the saints,
hearing of thy love and the faith which thou hast towards the Lord Jesus, and towards all the saints,
Philemon 1:3 Grace to you and peace from God our Father, and [the] Lord Jesus Christ.
Philemon 1:4 I thank my God, always making mention of thee at my prayers,
Philemon 1:5 hearing of thy love and the faith which thou hast towards the Lord Jesus, and towards all the saints,
Philemon 1:6 in such sort that thy participation in the faith should become operative in the acknowledgment of every good thing which is in us towards Christ [Jesus].
Philemon 1:7 For we have great thankfulness and encouragement through thy love, because the bowels of the saints are refreshed by thee, brother.
The verse centers on "faith", "hearing", "love", "thou", "hast", "towards", "lord", and "jesus". It is saying that the verse draws attention to "faith" and "hearing", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "I thank my God always making mention..." into verse 6's "in such sort that thy participation in...", so "faith" and "hearing" 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 "hearing" with trust shaped by these words, not by a vague optimism outside the passage.
