Charles H. Spurgeon on Psalms 119:105

Thy word is a lamp unto my feet, and a light unto my path. The use of a lamp is by night, while the light of the sun shineth by day. Whether it be day or night with us, we clearly understand our duty by the Word of God. The night signifieth adversity, and the day prosperity. Hence we may learn how to behave ourselves in all conditions. The word "path" notes our general choice and course of life; the word "feet" our particular actions. Now whether the matter, wherein we would be informed, concerneth our choice of the way that leadeth to true happiness, or our dexterous prosecution of the way, still the word of God will direct a humble and well disposed mind. Thomas Manton.
