"We are not called upon to enter into controversy with those who hold false theories. Controversy is unprofitable. Christ never entered into it. “It is written” is the weapon used by the world's Redeemer. Let us keep close to the Word. Let us allow the Lord Jesus and His messengers to testify. We know that their testimony is true. LS 93.1"
"But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God."
The EGW passage directly quotes "It is written" and connects it to Christ's method, which is a clear allusion to Matthew 4:4 and similar passages where Jesus uses scripture to refute temptation.
"Christ is over all the works of His creation. In the pillar of fire, He guided the children of Israel, His eyes seeing past, present, and future. He is to be recognized and honored by all who love God. His commandments are to be the controlling power in the lives of His people. LS 93.2"
"And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night:"
The EGW passage explicitly mentions the pillar of fire guiding the Israelites, directly referencing the event described in Exodus 13:21. This constitutes a clear thematic parallel.
"The tempter comes with the supposition that Christ has removed His seat of honor and power into some unknown region, and that men need no longer be inconvenienced by exalting His character and obeying His law. Human beings are to be a law unto themselves, he declares. These sophistries exalt self and make nothing of God. Restraint and moral control in the human family are destroyed. Restraint upon vice grows more and more feeble. The world loves not, fears not God. And those who do not love or fear God soon lose all sense of obligation to one another. They are without God and without hope in the world. LS 93.3"
"Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;"
Both passages discuss deception and a falling away from God's law. The EGW passage elaborates on the nature of the deception, while 2 Thessalonians 2:3 speaks of a general 'falling away.' The connection is thematic, but not a direct quote or explicit allusion.
