"I am instructed to say to students, In your search for knowledge climb higher than the standard set by the world; follow where Jesus has led the way. And to teachers I would say, Beware how you sow the seeds of unbelief in human hearts and minds. Cleanse yourselves from all filthiness of the flesh and spirit. The crowning glory of Christ's attributes is His holiness. The angels bow before Him in adoration, exclaiming, “Holy, holy, holy, Lord God Almighty.” Revelation 4:8 . He is declared to be glorious in His holiness. Study the character of God. By beholding Christ, by seeking Him in faith and prayer, you may become like Him. CT 402.2"
"And the four beasts had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, which was, and is, and is to come."
Ellen White directly references Revelation 4:8 in this passage.
"The standard of education in our schools is lowered as soon as Christ ceases to be the pattern of teachers and students. Teachers are to understand that their work is not confined to the knowledge contained in textbooks; it is to reach higher, far higher than it does. A course of self-discipline is to educate them to conform the character to the divine similitude. Self dies hard; but when teachers have that wisdom which comes from above, they will discern the true object of our educational work, and reforms will be made that will give our youth a training that is according to the Lord's plan of development. CT 402.3"
"For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren."
Both passages discuss conforming to a divine image (Christ's image, divine similitude). EGW applies this to education and the role of teachers, while Romans 8:29 speaks of God's predestination. The core idea of conforming to a divine standard connects them.
