The text begins with a proclamation of thanksgiving for the saints ("the cloud of witnesses") who confessed Christ and found in him protection and inspiration (st. 1-2). That proclamation is followed by a prayer for Christ's soldiers on earth to be "faithful, true, and bold" (st. 3). At the crux of the text is the confession of a "blest communion" of saints in heaven and on earth (st. 4). Though the holy warfare may be "fierce and long" (st. 5), "all the saints" may take courage from the vision of a victorious church that worships the triune God on that "more glorious day" (st. 6-7).
