"The Lord requires our teachers to put away from our schools those books teaching sentiments which are not in accordance with His word, and to give place to those books that are of the highest value. He will be honored when they show to the world that a wisdom more than human is theirs, because the Master Teacher is standing as their instructor. CT 389.2"
"To the law and to the testimony: if they speak not according to this word, it is because there is no light in them."
The EGW passage directly reflects the principle in Isaiah 8:20, which calls for testing all teachings against the law and testimony (God's word). EGW emphasizes the need to remove books that contradict God's word and replace them with those of higher value, aligning with the verse's call to adhere to God's word.
"There is need of separating from our educational work an erroneous, polluted literature, so that ideas which are the seeds of sin will not be received and cherished as the truth. Let not any suppose that a study of books which will lead to the reception of false ideas, is valuable education. Those ideas which, gaining entrance to the mind, separate the youth from the Source of all wisdom, all efficiency, all power, leave them the sport of Satan's temptations. A pure education for the youth in our schools, unmixed with heathen philosophy, is a positive necessity. CT 389.3"
"Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ."
Both passages warn against being led astray by worldly philosophies and traditions that are contrary to Christ. EGW's statement directly echoes the warning in Colossians 2:8 about being spoiled through philosophy and vain deceit.
"Keep thy heart with all diligence; for out of it are the issues of life."
Both passages emphasize the importance of guarding the heart/mind against negative influences. Proverbs 4:23 speaks of guarding the heart because it determines the course of life, and EGW speaks of guarding the mind from ideas that lead to sin.
