"The Bible is a book which discloses the principles of right and truth. It contains whatever is needful for the saving of the soul, and at the same time, it is adapted to strengthen and discipline the mind. If used as a text book in our schools, it will be found far more effective than any other book in the world, in guiding wisely in the affairs of this life, as well as in aiding the soul up the ladder of progress which reaches to heaven. God cares for us as intellectual beings, and he has given us his word as a lamp to our feet and a light to our pathway. “The entrance of thy words giveth light; it giveth understanding unto the simple.” [ Psalm 119:130 .] It is not the mere reading of the word that will accomplish the result that is designed by Heaven, but the truth revealed in the word of God must find an entrance into the heart, if the good intended is obtained. CE 108.1"
"The entrance of thy words giveth light; it giveth understanding unto the simple."
Ellen White directly references Psalms 119:130 in this passage.
The best educated in the sciences are not always the most effective instruments for God's use. There are many who find themselves laid aside, and those who have had fewer advantages of obtaining knowledge of books, taking their places, because the latter have a knowledge of practical things that is essential to the uses of every-day life; while those who consider themselves learned, often cease to be learners, are self-sufficient, and above being taught, even by Jesus, who was the greatest teacher the world ever knew. Those who have grown and expanded, whose reasoning faculties have been improved by deep searching of the Scriptures, that they may know the will of God, will come into positions of usefulness; for the word of God has had an entrance into their life and character. It must do its peculiar work, even to the piercing asunder of the joints and marrow, and discerning the thoughts and intents of the heart. God's word is to become the nourishment by which the Christian must grow …
"But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;"
Both passages discuss God's choice of the less conventionally qualified to accomplish His purposes. EGW elaborates on this theme, contrasting those with formal education who may become self-sufficient with those who are humble and receptive to God's word, aligning with the principle in 1 Corinthians 1:27.
