"we need men who have a deep knowledge of the Scriptures, men who can teach these lessons to others clearly and simply, just as Christ taught His disciples that which He deemed most essential. CT 484.2"
"Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."
Both passages discuss teaching others, with Matthew 28:20 focusing on teaching Christ's commands and the EGW passage focusing on teaching the Scriptures clearly and simply.
"And the needed knowledge will be given to all who come to Christ, receiving and practicing His teachings, making His word a part of their lives. The Holy Spirit teaches the student of the Scriptures to judge all things by the standard of righteousness and truth and justice. The divine revelation supplies him with the knowledge that he needs. Those who place themselves under the instruction of the great Medical Missionary, to be workers together with Him, will have a knowledge that the world, with all its traditionary lore, cannot supply. CT 484.3"
"But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."
Both passages highlight the role of the Holy Spirit in teaching and providing knowledge, especially in understanding spiritual matters.
