Jamieson, Fausset & Brown

In order to "rejoice evermore," we must "pray without ceasing" (Th1 5:17). He who is wont to thank God for all things as happening for the best, will have continuous joy [THEOPHYLACT]. Eph 6:18; Phi 4:4, Phi 4:6, "Rejoice in the Lord . . . by prayer and supplication with thanksgiving"; Rom 14:17, "in the Holy Ghost"; Rom 12:12, "in hope"; Act 5:41, "in being counted worthy to suffer shame for Christ's name"; Jam 1:2, in falling "into divers temptations."
