"“Labor not for the meat which perisheth,” Christ admonished, “but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for Him hath God the Father sealed.” John 6:27 . When we obey these words, we shall rightly understand the teachings of the Scriptures, and esteem the truth as the most valuable treasure with which to store the mind. We shall have within us a wellspring of the water of life. We shall pray, as did the psalmist, “Open Thou mine eyes, that I may behold wondrous things out of Thy law;” and we shall find, as he did, that “the judgments of the Lord are true and righteous altogether. More to be desired are they than gold, yea, than much fine gold: sweeter also than honey and the honeycomb. Moreover by them is Thy servant warned: and in keeping of them there is great reward.” Psalm 119:18 ; 19:9-11 . CT 31.1"
"Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed."
EGW directly quotes John 6:27, making it a clear explicit allusion.
"Open thou mine eyes, that I may behold wondrous things out of thy law."
EGW directly quotes Psalms 119:18, making it a clear explicit allusion.
"***** It is only life that can beget life. He alone has life who is connected with the Source of life, and only such can be a channel of life. In order that the teacher may accomplish the object of his work, he should be a living embodiment of truth, a living channel through which wisdom and life may flow. A pure life, the result of sound principles and right habits, should therefore be regarded as his most essential qualification. CT 31.2"
"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 sentiment of John 15:5 about the necessity of being connected to the source of life (Christ) to bear fruit. The teacher needs to be connected to Christ to impart life to students.
