"The great aim of the teacher should be the perfecting of Christian character in himself and in his students. Teachers, let your lamps be trimmed and burning, and they will not only be lights to your students, but will send out clear and distinct rays to the homes and neighborhoods where your students live, and far beyond into the moral darkness of the world.— Special Testimonies On Education, 47-52 ; written May 15, 1896.

"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
EGW's statement about letting lamps be trimmed and burning, sending out light, is a clear allusion to Matthew 5:16. The concept of shining light to the world is directly echoed.
