"Those who give themselves up to the sorcery of Satan, may boast of great benefit received; but does this prove their course to be wise or safe? What if life should be prolonged? What if temporal gain should be secured? Will it pay in the end to have disregarded the will of God? All such apparent gain will prove at last an irrecoverable loss. We cannot with impunity break down a single barrier which God has erected to guard His people from Satan's power. PK 212.1"
"For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?"
Both passages emphasize the ultimate futility of gaining worldly benefits at the expense of one's spiritual well-being. The EGW passage applies this to seeking help from Satan, while Matthew 16:26 speaks of gaining the whole world but losing one's soul.
"As Ahaziah had no son, he was succeeded by Jehoram, his brother, who reigned over the ten tribes for twelve years. Throughout these years his mother, Jezebel, was still living, and she continued to exercise her evil influence over the affairs of the nation. Idolatrous customs were still practiced by many of the people. Jehoram himself “wrought evil in the sight of the Lord; but not like his father, and like his mother: for he put away the image of Baal that his father had made. Nevertheless he cleaved unto the sins of Jeroboam the son of Nebat, which made Israel to sin; he departed not therefrom.” 2 Kings 3:2, 3 . PK 212.2"
"And it came to pass, as if it had been a light thing for him to walk in the sins of Jeroboam the son of Nebat, that he took to wife Jezebel the daughter of Ethbaal king of the Zidonians, and went and served Baal, and worshipped him."
EGW is elaborating on the context and consequences of the sin mentioned in 1 Kings 16:31, specifically the influence of Jezebel and the continuation of Jeroboam's sins. It's more than a thematic parallel; it's a direct application of the principle of influence and consequence.
"It was during Jehoram's reign over Israel that Jehoshaphat died, and Jehoshaphat's son, also named Jehoram, ascended the throne of the kingdom of Judah. By his marriage with the daughter of Ahab and Jezebel, Jehoram of Judah was closely connected with the king of Israel; and in his reign he followed after Baal, “like as did the house of Ahab.” “Moreover he made high places in the mountains of Judah, and caused the inhabitants of Jerusalem to commit fornication, and compelled Judah thereto.” 2 Chronicles 21:6, 11 . PK 212.3"
"And he walked in the way of the kings of Israel, like as did the house of Ahab: for he had the daughter of Ahab to wife: and he wrought that which was evil in the eyes of the Lord."
EGW directly quotes and references 2 Chronicles 21:6, making it a clear explicit allusion.
"Moreover he made high places in the mountains of Judah, and caused the inhabitants of Jerusalem to commit fornication, and compelled Judah thereto."
EGW directly quotes and references 2 Chronicles 21:11, making it a clear explicit allusion.
