"Chapter 9—The Treasure with Which to Store the Mind Jesus beheld the human race, ignorant, apostate from God, standing under the penalty of the broken law; and he came to bring deliverance, to offer a complete pardon, signed by the Majesty of heaven. If man will accept this pardon, he may be saved; if he rejects it, he will be lost. The wisdom of God alone can unfold the mysteries of the plan of salvation. The wisdom of men may or may not be valuable, as experience shall prove, but the wisdom of God is indispensable; and yet many who profess to be wise are willingly ignorant of the things that pertain to eternal life. Miss what you may in the line of human attainments, but you must have faith in the pardon brought to you at infinite cost, or all of wisdom attained in earth, will perish with you. CE 78"
"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."
EGW's passage directly reflects the core message of John 3:16. Both emphasize God's gift of salvation through Jesus, offering pardon and eternal life to those who believe, and the consequence of rejecting this offer.
"darkness of eternal night. Jesus spake as never man spake. He poured out to men the whole treasure of heaven in wisdom and knowledge. He is the light that lighteth every man who cometh into the world. Every phase of truth was evident to him. He did not come to utter uncertain sentiments and opinions; but only to speak truth established upon eternal principles. Then why take the unstable words of men as exalted wisdom, when a greater and certain wisdom is at your command? Men take the writings of scientists, falsely so-called, and seek to make their deductions harmonize with the statements of the Bible. But where there is no agreement, there can be no harmony. Christ declares, “No man can serve two masters.” [ Matthew 6:24 .] Their interests are sure to clash. Again and again men have attempted to put the Bible and the writings of men upon a common basis; but the attempt has proved a failure; for we cannot serve God and mammon. CE 78.2"
"No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon."
Ellen White directly references Matthew 6:24 in this passage.
"That was the true Light, which lighteth every man that cometh into the world."
EGW directly quotes and applies John 1:9 to Jesus, emphasizing His role as the source of true light and wisdom.
