"Christ said to His disciples: “Ye are the light of the world.” Matthew 5:14 . Then how important it is that every soul shall keep his light trimmed and burning, that he may give light to all with whom he comes in contact. God has made His people the depositaries of sacred truth. Talents have been committed to them for wise improvement, for God designs that by constant use their talents shall be multiplied. 8T 141.2"
"Ye are the light of the world. A city that is set on an hill cannot be hid."
Ellen White directly references Matthew 5:14 in this passage.
