"Every seed sown produces a harvest of its kind. So it is in human life. We all need to sow the seeds of compassion, sympathy, and love; for we shall reap what we sow. Every characteristic of selfishness, self-love, self-esteem, every act of self-indulgence, will bring forth a like harvest. He who lives for self is sowing to the flesh, and of the flesh he will reap corruption. COL 84.3"
"Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap."
The EGW passage directly echoes and expands upon the principle stated in Galatians 6:7, applying it to various aspects of human behavior and their consequences.
"God destroys no man. Everyone who is destroyed will have destroyed himself. Everyone who stifles the admonitions of conscience is sowing the seeds of unbelief, and these will produce a sure harvest. By rejecting the first warning from God, Pharaoh of old sowed the seeds of obstinacy, and he reaped obstinacy. God did not compel him to disbelieve. The seed of unbelief which he sowed produced a harvest of its kind. Thus his resistance continued, until he looked upon his devastated land, upon the cold, dead form of his first-born, and the first-born of all in his house and of all the families in his kingdom, until the waters of the sea closed over his horses and his chariots and his men of war. His history is a fearful illustration of the truth of the words that “whatsoever a man soweth, that shall he also reap.” Galatians 6:7 . Did men but realize this, they would be careful what seed they sow. COL 84.4"
"Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap."
Ellen White directly references Galatians 6:7 in this passage.
