"Others, however, fail of a satisfactory understanding of the great problem of evil, from the fact that tradition and misinterpretation have obscured the teaching of the Bible concerning the character of God, the nature of His government, and the principles of His dealing with sin. GC 492.1"
"For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts."
Isaiah 55:8-9 speaks of God's ways being higher than man's, which is directly related to the difficulty in understanding God's character and dealings with sin, as mentioned in the EGW quote. The EGW quote implies that understanding God is difficult because His ways are not our ways, which is the principle stated in Isaiah.
"As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction."
Both passages discuss the difficulty some have in understanding scripture, leading to misinterpretations. EGW focuses on the character of God and the problem of evil, while Peter discusses the twisting of scripture by the unlearned. The connection is thematic, but not a direct principle.
"It is impossible to explain the origin of sin so as to give a reason for its existence. Yet enough may be understood concerning both the origin and the final disposition of sin to make fully manifest the justice and benevolence of God in all His dealings with evil. Nothing is more plainly taught in Scripture than that God was in no wise responsible for the entrance of sin; that there was no arbitrary withdrawal of divine grace, no deficiency in the divine government, that gave occasion for the uprising of rebellion. Sin is an intruder, for whose presence no reason can be given. It is mysterious, unaccountable; to excuse it is to defend it. Could excuse for it be found, or cause be shown for its existence, it would cease to be sin. Our only definition of sin is that given in the word of God; it is “the transgression of the law;” it is the outworking of a principle at war with the great law of love which is the foundation of the divine government. GC 492.2"
"Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:"
James 1:13 states that God cannot be tempted with evil and does not tempt anyone. This directly supports EGW's statement that God was in no way responsible for the entrance of sin. The principle that God is not the source of temptation or evil directly aligns with EGW's assertion of God's non-responsibility for sin.
"Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?"
Both passages address the limitations of human understanding when questioning God's actions. Romans 9:20 questions man's right to question God's creation, while EGW discusses the impossibility of fully explaining the origin of sin. Both suggest a limit to human comprehension when dealing with divine matters.
