My soul, be on thy guard: Ten thousand foes arise, The host of sin are pressing hard, To draw thee from the skies. O watch and fight and pray, The battle ne'er give o'er. Renew it boldly ev'ry day; And help divine implore. Ne'er think the vict'ry won, Nor lay thy armor down; Thy ard'ous work will not be done, Till thou obtain thy crown.
