Passage
the grace of our Lord Jesus Christ <FI>is<Fi> with you all. Amen.
the grace of our Lord Jesus Christ <FI>is<Fi> with you all. Amen.
Philippians 4:21 Salute ye every saint in Christ Jesus; there salute you the brethren with me;
Philippians 4:22 there salute you all the saints, and specially those of Caesar's house;
Philippians 4:23 the grace of our Lord Jesus Christ <FI>is<Fi> with you all. Amen.
The verse centers on "grace", "lord", "jesus", "christ", and "amen". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The prior verse says "there salute you all the saints and...", giving immediate footing for "grace" and "lord". In Philippians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grace" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
