Passage
Grace to you and peace from God our Father, and [the] Lord Jesus Christ.
Grace to you and peace from God our Father, and [the] Lord Jesus Christ.
Philemon 1:1 Paul, prisoner of Christ Jesus, and Timotheus the brother, to Philemon the beloved and our fellow-workman,
Philemon 1:2 and to the sister Apphia and to Archippus our fellow-soldier, and to the assembly which [is] in thine house.
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,
The verse centers on "grace", "peace", "father", "lord", "jesus", and "christ". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The nearby context moves from verse 2's "and to the sister Apphia and to..." into verse 4's "I thank my God always making mention...", so "grace" and "peace" 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 "grace" and "peace" with trust shaped by these words, not by a vague optimism outside the passage.
