"From being one of the greatest kings that ever wielded a scepter, Solomon became a profligate, the tool and slave of others. His character, once noble and manly, became enervated and effeminate. His faith in the living God was supplanted by atheistic doubts. Unbelief marred his happiness, weakened his principles, and degraded his life. The justice and magnanimity of his early reign were changed to despotism and tyranny. Poor, frail human nature! God can do little for men who lose their sense of dependence upon Him. PK 58.1"
"Pride goeth before destruction, and an haughty spirit before a fall."
Both passages address the downfall of Solomon. Proverbs 16:18 speaks of pride leading to destruction, and EGW describes Solomon's descent from greatness to a state of moral decay, which can be seen as a consequence of pride and a loss of dependence on God.
"During these years of apostasy, the spiritual decline of Israel progressed steadily. How could it be otherwise when their king had united his interests with satanic agencies? Through these agencies the enemy worked to confuse the minds of the Israelites in regard to true and false worship, and they became an easy prey. Commerce with other nations brought them into intimate contact with those who had no love for God, and their own love for Him was greatly lessened. Their keen sense of the high, holy character of God was deadened. Refusing to follow in the path of obedience, they transferred their allegiance to the enemy of righteousness. It came to be a common practice to intermarry with idolaters, and the Israelites rapidly lost their abhorrence of idol worship. Polygamy was countenanced. Idolatrous mothers brought their children up to observe heathen rites. In the lives of some, the pure religious service instituted by God was replaced by idolatry of the darkest hue. PK 58.2"
"Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened."
Both passages describe a decline in spiritual understanding and practice. Romans 1:21 speaks of people knowing God but not glorifying Him, leading to darkened hearts. EGW describes Israel's spiritual decline due to intermarriage, idolatry, and a loss of love for God. The themes are closely aligned.
