Though he was a prisoner, Paul was not discouraged. Instead, a note of triumph rings through the letters that he wrote from Rome to the churches. "Rejoice in the Lord alway," he wrote to the Philippians, "and again I say, Rejoice. . . . Be careful for nothing; but in everything by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things."

Skønt Paulus var fange, tabte han ikke modet. Tværtimod lyder der en sejrsklang gennem de breve, han fra Rom skrev til menighederne. "Glæd jer altid i Herren " skrev han til filipperne, "jeg siger igen: glæd jer! ..... Vær ikke bekymrede for noget, men lad i alle ting jeres ønsker komme frem for Gud, idet I beder og bønfalder under taksigelse; så skal Guds fred, som overgår al forstand, bevare jeres hjerter og jeres tanker i Kristus Jesus. I øvrigt, brødre! alt, hvad der er sandt, hvad der er sømmeligt, hvad der er retskaffent, hvad der er rent, hvad der er elskeligt, hvad der har godt lov, al dyd og alt, hvad der er ros værd: det skal I have i tanke!"
