"As you have opportunity, speak to the workers; speak words that will be a strength and an inspiration. We are altogether too indifferent in regard to one another. Too often we forget that our fellow laborers are in need of strength and cheer. In times of special perplexity and burden, take care to assure them of your interest and sympathy. While you try to help them by your prayers, let them know that you do it. Send along the line God's message to His workers: “Be strong and of a good courage.” Joshua 1:6 . 7T 185.2"
"Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them."
Ellen White directly references Joshua 1:6 in this passage.
"Better, far better might your children suffer, better lie in their graves, than be taught to treat lightly the principles that lie at the very foundation of loyalty to truth, to their fellow beings, and to God. 7T 185.4"
"And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell."
The EGW passage emphasizes the importance of prioritizing loyalty to truth and God over physical safety or comfort, even to the point of death. This reflects the principle in Matthew 10:28, which encourages believers to fear God, who has power over both body and soul, rather than those who can only harm the body.
