"The work of Christ is to draw men from the false and spurious to the true and genuine. “He that followeth me shall not walk in darkness, but shall have the light of life.” [ John 8:12 .] There is no danger of going into error while we follow in the footsteps of “the Light of the world.” We are to work the works of Christ. We must engage heart and soul in his service; we must search the word of life, and present it to others. We must educate the people to realize the importance of its teaching, and the danger of deviating from its plain commands. CE 121.1 The Jews were led into error and ruin, and to the rejection of the Lord of glory, because they knew not the Scriptures, nor the power of God. A great work is before us,—to lead men to take God's word as the rule of their lives, to make no compromise with tradition and custom, but to walk in all the commandments and ordinances of the Lord.— The Review and Herald, July 17, 1888 . CE 121.2"
"Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life."
EGW directly quotes John 8:12 and builds her argument upon it.
