D its lonely hours and dreary, When we Close the aching sight, Musing sadly, lorn and weary, Trusting that tomorrow's light May reveal a day more cheery; Amid affliction's darker hour, When no hope beguiles our sadness, When Death's hurtling tempests lower, And forever shroud our gladness, While Grief's unrelenting power Goads our stricken hearts to madness; When from friends beloved we're parted, And from scenes our spirits love, And are driven, broken-hearted, O'er a heartless world to rove; When the woes by which we've smarted, Vainly seek to melt or move; When we trust and are deluded, When we love and are denied, When the schemes o'er which we brooded Burst like mist on mountain's side, And, from every hope excluded, We in dark despair abide; Then, and ever, God sustains us, He whose eye no slumber knows, Who controls each throb that pains us, And in mercy sends our woes, And by love severe constrains us To avoid eternal throes.
