"And more than this is wrapped up in the sowing and the reaping. As we distribute God's temporal blessings, the evidence of our love and sympathy awakens in the receiver gratitude and thanksgiving to God. The soil of the heart is prepared to receive the seeds of spiritual truth. And He who ministers seed to the sower will cause the seed to germinate and bear fruit unto eternal life. COL 86.1"
"Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness;)"
Both passages connect the act of giving (temporal blessings or seed) with spiritual growth and God's provision. EGW expands on the idea of preparing the heart to receive spiritual truth, which aligns with the concept of God multiplying the seed sown and increasing the fruits of righteousness.
"***** By the casting of the grain into the soil, Christ represents the sacrifice of Himself for our redemption. “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 . So the death of Christ will result in fruit for the kingdom of God. In accordance with the law of the vegetable kingdom, life will be the result of His death. COL 86.2"
"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.
"Those who for Christ's sake sacrifice their life in this world, will keep it unto life eternal. COL 86.3"
"For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it."
The EGW passage is a clear restatement of the principle found in Matthew 16:25, emphasizing the sacrifice of earthly life for eternal life in Christ.
