ISB ~ Philippians 4 v4

Rejoice … Rejoice:Repeated for emphasis. The joy of the Lord is produced in believers by the Holy Spirit (Gal 5:22) and can flourish despite trying circumstances and even crushing misfortunes (Mt 5:11-12; Jas 1:2). Paul exemplifies this in Philippians, where a spirit of gladness dominates the tone of his letter even though he is writing from prison.
