"In searching the pages of God's word, 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. How wonderful, how almost incredible, it is that the infinite God would consent to the humiliation of His only-begotten Son! Let students contemplate this great thought. They will not come from such contemplation without being elevated, purified, ennobled. CT 448.2"
"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 highlight God's love for the world demonstrated through the sacrifice of his Son, Jesus. The EGW passage expands on the contemplation of this sacrifice and its elevating effect, directly echoing the core theme of John 3:16.
"God's word is the spiritual food by which the Christian must grow strong in spirit and in intellect, that he may do battle for truth and righteousness. The Bible teaches that every besetting sin must be put away, that the warfare against evil must be waged until every wrong is overcome. The human agent must place himself as a willing student in the school of Christ. As he accepts the grace freely offered him, the presence of the Saviour in the thoughts and in the heart will give him decision of purpose to lay aside every weight, that the heart may be filled with all the fullness of God. CT 448.3"
"Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us,"
The EGW passage directly alludes to Hebrews 12:1, using the phrase 'lay aside every weight' and referencing the concept of 'besetting sin.'
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Both passages discuss the Christian's struggle against evil. Ephesians 6:12 describes the spiritual warfare against principalities and powers, while the EGW passage speaks of putting away sin and waging warfare against evil. The EGW passage elaborates on the means of victory through spiritual food (God's word) and the grace of Christ.
"And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God."
Both passages speak of being 'filled with all the fullness of God.' While not a direct quote, the thematic connection is clear and significant.
