"“We shall find it necessary to establish our schools out of, and away from, the cities, and yet not so far away that they cannot be in touch with them, to do them good, to let light shine amid the moral darkness. Students need to be placed under the most favorable circumstances to counteract very much of the education they have received.... LS 352.1"
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
EGW's phrase 'let light shine amid the moral darkness' is a clear allusion to Matthew 5:16, which speaks of letting one's light shine before men.
"“We need schools in this country to educate children and youth that they may be masters of labor, and not slaves of labor. Ignorance and idleness will not elevate one member of the human family. Ignorance will not lighten the lot of the hard toiler. Let the worker see what advantage he may gain in the humblest occupation, by using the ability God has given him as an endowment. Thus he can become an educator, teaching others the art of doing work intelligently. He may understand what it means to love God with the heart, the soul, the mind, and the strength. The physical powers are to be brought into service for love to God. The Lord wants the physical strength, and you can reveal your love for Him by the right use of your physical powers, doing the very work which needs to be done. There is no respect of persons with God.... LS 352.2"
"Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind."
EGW directly quotes and expands upon the concept of loving God with heart, soul, and mind, making it a clear and explicit allusion to Matthew 22:37.
"“There is in the world a great deal of hard, taxing work to be done; and he who labors without exercising the God-given powers of mind and heart and soul, he who employs the physical strength alone, makes the work a wearisome tax and burden. There are men with mind, heart, and soul who regard work as a drudgery, and settle down to it with self-complacent ignorance, delving without thought, without taxing the mental capabilities in order to do the work better. LS 352.3"
"If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct."
Both passages discuss the importance of applying wisdom and skill to work. Ecclesiastes 10:10 highlights the inefficiency of using a blunt tool without sharpening it, while EGW emphasizes the need to engage the mind and heart in labor to avoid it becoming a wearisome burden.
