"***** In our work for the poor and unfortunate, we shall need to be guarded, lest we gather responsibilities which we shall not be able to carry. Before adopting plans and methods that require a large outlay of means, we are to consider whether they bear the divine signature. God does not sanction the pushing forward of one line of work without regard to other lines. He designs that the medical missionary work shall prepare the way for the presentation of the saving truth for this time, the proclamation of the third angel's message. If this design is met, the message will not be eclipsed nor its progress hindered. 6T 293.1"
"For the body is not one member, but many."
Both passages emphasize the importance of different parts working together for a common goal. The EGW passage speaks of different lines of work, while 1 Corinthians 12:14 speaks of different members of the body.
"***** It is not numerous institutions, large buildings, or great display that God requires, but the harmonious action of a peculiar people, a people chosen by God and precious. Every man is to stand in his lot and place, thinking, speaking, and acting in harmony with the Spirit of God. Then, and not till then, will the work be a complete, symmetrical whole. 6T 293.2"
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
The EGW passage directly references the concept of a 'peculiar people' chosen by God, which is a clear allusion to 1 Peter 2:9.
