"Had Solomon continued in humility of mind to turn the attention of men from himself to the One who had given him wisdom and riches and honor, what a history might have been his! But while the pen of inspiration records his virtues, it also bears faithful witness to his downfall. Raised to a pinnacle of greatness and surrounded with the gifts of fortune, Solomon became dizzy, lost his balance, and fell. Constantly extolled by men of the world, he was at length unable to withstand the flattery offered him. The wisdom entrusted to him that he might glorify the Giver, filled him with pride. He finally permitted men to speak of him as the one most worthy of praise for the matchless splendor of the building planned and erected for the honor of “the name of the Lord God of Israel.” PK 68.1"
"Wherefore let him that thinketh he standeth take heed lest he fall."
The EGW passage describes Solomon's fall due to pride and being lifted up. The verse from 1 Corinthians warns against being overconfident and falling. The connection is that pride and self-exaltation can lead to a downfall, which is a clear thematic parallel.
"Pride goeth before destruction, and an haughty spirit before a fall."
Both passages connect pride with downfall. The EGW passage describes Solomon's pride leading to his fall, while Proverbs 16:18 states the general principle that pride precedes destruction. The EGW passage provides a specific example illustrating the proverb.
"Thus it was that the temple of Jehovah came to be known throughout the nations as “Solomon's temple.” The human agent had taken to himself the glory that belonged to the One “higher than the highest.” Ecclesiastes 5:8 . Even to this day the temple of which Solomon declared, “This house which I have built is called by Thy name” ( 2 Chronicles 6:33 ), is oftenest spoken of, not as the temple of Jehovah, but as “Solomon's temple.” PK 68.2 Man cannot show greater weakness than by allowing men to ascribe to him the honor for gifts that are Heaven-bestowed. The true Christian will make God first and last and best in everything. No ambitious motives will chill his love for God; steadily, perseveringly, will he cause honor to redound to his heavenly Father. It is when we are faithful in exalting the name of God that our impulses are under divine supervision, and we are enabled to develop spiritual and intellectual power. PK 68.3"
"If thou seest the oppression of the poor, and violent perverting of judgment and justice in a province, marvel not at the matter: for he that is higher than the highest regardeth; and there be higher than they."
Ellen White directly references Ecclesiastes 5:8 in this passage.
"Then hear thou from the heavens, even from thy dwelling place, and do according to all that the stranger calleth to thee for; that all people of the earth may know thy name, and fear thee, as doth thy people Israel, and may know that this house which I have built is called by thy name."
Ellen White directly references 2 Chronicles 6:33 in this passage.
