Boyd K. Packer
"Another scripture is very important for a teacher to understand: 'All men are instructed sufficiently that they know good from evil.' (2 Nephi 2:5; Helaman 14:31.)
"Parents and teachers need to know that a youngster can tell right from wrong. This knowledge may be distorted or perverted or covered up in unfortunate life experiences, but intuitively, as a part of the spiritual endowment of all humanity, there is a knowledge of right from wrong.
"That gives me great hope, for then I understand that every child of God, however reprobate he may have become, however degenerate he may seem to be, has hidden within him the spark of divinity and a sensitivity to that which is wrong as compared to that which is right." (Teach Ye Diligently, p. 99-100)
