"become fools in their own estimation. The greatest ignorance that now curses the human race is in regard to the binding claims of the law of God; and this ignorance is the result of neglecting the study of the word of God. It is Satan's determined plan to so engage and absorb the mind, that God's great guide book shall not be the Book of books, and that the sinner may not be led from the path of transgression to the path of obedience. CE 107.1"
"For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness."
Both passages discuss the foolishness of worldly wisdom compared to God's wisdom. The EGW passage specifically mentions ignorance of God's law, which is a form of worldly wisdom that is foolish in God's eyes.
"The Bible is not exalted to its place, and yet of what infinite importance it is to the souls of men. In searching its pages, we move through scenes majestic and eternal. We behold Jesus, the Son of God, coming to our world, and engaging in the mysterious conflict that discomfited the powers of darkness. O how wonderful, how almost incredible it is, that the infinite God would consent to the humiliation of his own dear Son! Let every student of the Scriptures contemplate this great fact, and he will not come from such a contemplation without being elevated, purified, and ennobled. CE 107.2"
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."
Both passages emphasize God's love demonstrated through the sacrifice of his Son, Jesus. EGW expands on the implications of this sacrifice and its effect on those who contemplate it, directly echoing the core message of John 3:16.
