"More than this: as we impart the blessings of this life, gratitude in the recipient prepares the heart to receive spiritual truth, and a harvest is produced unto life everlasting. Ed 110.1"
"And whosoever shall give to drink unto one of these little ones a cup of cold water only in the name of a disciple, verily I say unto you, he shall in no wise lose his reward."
Both passages connect acts of kindness with spiritual reward. The EGW passage expands on the idea that showing kindness can prepare someone to receive spiritual truth, while Matthew 10:42 promises a reward for even a small act of kindness done in the name of a disciple. The connection is thematic, but not a direct quotation or explicit allusion.
"By the casting of grain into the earth, the Saviour represents His sacrifice for us. “Except a corn of wheat fall into the ground and die,” He says, “it abideth alone: but if it die, it bringeth forth much fruit.” John 12:24 . Only through the sacrifice of Christ, the Seed, could fruit be brought forth for the kingdom of God. In accordance with the law of the vegetable kingdom, life is the result of His death. Ed 110.2"
"Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit."
Ellen White directly references John 12:24 in this passage.
"So with all who bring forth fruit as workers together with Christ: self-love, self-interest, must perish; the life must be cast into the furrow of the world's need. But the law of self-sacrifice is the law of self-preservation. The husbandman preserves his grain by casting it away. So the life that will be preserved is the life that is freely given in service to God and man. Ed 110.3"
"Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit."
The EGW passage directly echoes the principle of John 12:24, using the analogy of a seed dying to produce fruit to illustrate the necessity of self-sacrifice for spiritual growth and service. The connection is clear and intentional.
