573 How shall the young secure their hearts,

1 How shall the young secure their hearts, And guard their lives from sin? Thy word the choicest rules imparts To keep the conscience clean. 2 'Tis, like the sun, a heavenly light, That guides us all the day; And through the dangers of the night A lamp to lead our way. 3 The starry heavens Thy rule obey, The earth maintains her place; And these Thy servants, night and day, Thy skill and power express. 4 But still Thy law and gospel, Lord, Have lessons more divine; Not earth stands firmer than Thy word, Nor stars so nobly shine. 5 Thy word is everlasting truth: How pure is every page! That holy book shall guide our youth, And well support our age.
