Thou great Instructor, lest I stray, Oh! teach my erring feet Thy way: Thy truth, with ever fresh delight; Shall guide my doubtful steps aright. How oft my heart's affections yield, And wander o'er the world's wide field, My roving passions, Lord, reclaim, Unite them all to fear Thy name. Then, to my God, my heart and tongue, With all their pow'rs, shall raise the song: On earth Thy glories I'll declare, Till heav'n th'immortal notes shall hear.
