2. Continue—Greek, "Continue perseveringly," "persevere" (Eph 6:18), "watching thereunto"; here, "watch in the same," or "in it," that is, in prayer: watching against the indolence as to prayer, and in prayer, of our corrupt wills.
with thanksgiving—for everything, whether joyful, or sorrowful, mercies temporal and spiritual, national, family, and individual (1Co 14:17; Php 4:6; 1Th 5:18).
