"I have been shown that the greatest reason why the people of God are now found in this state of spiritual blindness is that they will not receive correction. Many have despised the reproofs and warnings given them. The True Witness condemns the lukewarm condition of the people of God, which gives Satan great power over them in this waiting, watching time. The selfish, the proud, and the lovers of sin are ever assailed with doubts. Satan has ability to suggest doubts and to devise objections to the pointed testimony that God sends, and many think it a virtue, a mark of intelligence in them, to be unbelieving and to question and quibble. Those who desire to doubt will have plenty of room. God does not propose to remove all occasion for unbelief. He gives evidence, which must be carefully investigated with a humble mind and a teachable spirit, and all should decide from the weight of evidence. 3T 255.1"
"The fear of the Lord is the beginning of knowledge: but fools despise wisdom and instruction."
The EGW passage discusses the rejection of correction and the consequences of spiritual blindness, which aligns with the principle in Proverbs 1:7 that fools despise wisdom and instruction. While not a direct quote, the underlying principle is shared.
