"In every generation and in every land the true foundation and pattern for character building have been the same. The divine law, “Thou shalt love the Lord thy God with all thy heart; ... and thy neighbor as thyself” ( Luke 10:27 ), the great principle made manifest in the character and life of our Saviour, is the only secure foundation and the only sure guide. Ed 228.4"
"And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself."
Ellen White directly references Luke 10:27 in this passage.
