"One of the chief advantages of Loma Linda is the pleasing variety of charming scenery on every side. The extensive view of valley and mountain is magnificent. But more important than magnificent scenery and beautiful buildings and spacious grounds is the close proximity of this institution to a densely populated district and the opportunity thus afforded of communicating to many, many people a knowledge of the third angel's message. We are to have clear spiritual discernment, else we shall fail of discerning the opening providences of God that are preparing the way for us to enlighten the world. 9T 173.2"
"And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,"
EGW mentions the importance of communicating the third angel's message, directly referencing Revelation 14:9. The connection is thematic, linking the location of Loma Linda with the mission of spreading this specific message.
"With the possession of this place comes the weighty responsibility of making the work of the institution educational in character. Loma Linda is to be not only a sanitarium, but an educational center. A school is to be established here for the training of gospel medical missionary evangelists. Much is involved in this work, and it is very essential that a right beginning be made. The Lord has a special work to be done in this field. He instructed me to call on Elder and Mrs. Haskell to help us in getting properly started a work similar to that which they had carried on at Avondale. Laborers of experience have consented to unite with the forces at Loma Linda to develop the school that must be carried on there. As they go forward in faith, the Lord will go before them, preparing the way. 9T 173.3"
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 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."
EGW's description of establishing an educational center for training medical missionary evangelists at Loma Linda directly reflects the Great Commission in Matthew 28:19-20. The principle of going and teaching is central to both passages.
