"All self-uplifting works out the natural result—making character of which God cannot approve. Work and teach; work in Christ's lines, and then you will never work in your own weak ability, but will have the co- operation of the divine. CT 283.1"
"I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing."
The EGW passage echoes the principle of John 15:5, emphasizing dependence on Christ for effective work and teaching, contrasting it with reliance on one's own abilities.
"“Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.” Verse 8 . He is on the playground, watching your amusements, and catching every soul whom he finds off guard, sowing his seeds in human hearts, and gaining control of human minds. He is present in every exercise in the schoolroom. Those students who allow their minds to be deeply excited over games are not in the best condition to receive the instruction, the counsel, the reproof, most essential for them. CT 283.2"
"Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:"
EGW directly quotes 1 Peter 5:8.
"Put on the whole armour of God, that ye may be able to stand against the wiles of the devil."
The EGW passage shares the theme of spiritual warfare and the devil's attempts to deceive and control minds, which is also present in Ephesians 6:11, although the connection is less direct than a quote or explicit allusion.
"Physical exercise was marked out by the God of wisdom. Some hours each day should be devoted to useful education in lines of work that will help the students in learning the duties of practical life, which are essential for all our youth. CT 283.3"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage advocates for physical exercise and useful work, aligning with the principle of glorifying God in one's body as stated in 1 Corinthians 6:19-20. The verse emphasizes the body as a temple, and EGW's counsel promotes its proper care through activity.
