"The teacher who is severe, critical, overbearing, heedless of others’ feelings, must expect the same spirit to be manifested toward himself. He who wishes to preserve his own dignity and self-respect, must be careful not to wound needlessly the self-respect of others. This rule should be sacredly observed toward the dullest, the youngest, the most blundering scholars. What God intends to do with those apparently uninteresting youth, you do not know. He has, in the past, accepted persons no more promising or attractive, to do a great work for him. His Spirit moving upon the heart has aroused every faculty to vigorous action. The Lord saw in those rough, unhewn stones, precious material, that would stand the test of storm and heat and pressure. God seeth not as man sees. He judges not from appearances, but he searches the heart, and judges righteously. CE 41.1"
"For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again."
Both passages highlight the principle of reciprocity in judgment and treatment of others. EGW applies this principle specifically to the teacher-student relationship, emphasizing the importance of respecting others' self-worth.
"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 emphasize God's ability to use seemingly unlikely or unpromising individuals for great purposes. EGW applies this to students, while 1 Corinthians speaks more broadly about God's choice of the foolish and weak.
