"The love of truth, and a sense of the responsibility to glorify God, are the most powerful of all incentives to the improvement of the intellect. With this impulse to action the student cannot be a trifler. He will be always in earnest. He will study as under the eye of God, knowing that all heaven is enlisted in the work of his education. He will become noble-minded, generous, kind, courteous, Christlike, efficient. Heart and mind will work in harmony with the will of God. CT 226.1"
"Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God."
EGW's emphasis on glorifying God as a powerful incentive for intellectual improvement directly reflects the principle in 1 Corinthians 10:31, which calls for doing everything to the glory of God. EGW applies this principle specifically to the context of education and personal development.
