"A Failure To Honor God One who sees beneath the surface, who reads the hearts of all men, says of those who have had great light: “They are not afflicted and astonished because of their moral and spiritual condition.” “Yea, they have chosen their own ways, and their soul delighteth in their abominations. I also will choose their delusions, and will bring their fears upon them; because when I called, none did answer; when I spake, they did not hear: but they did evil before Mine eyes, and chose that in which I delighted not.” “God shall send them strong delusion, that they should believe a lie,” “because they received not the love of the truth, that they might be saved,” “but had pleasure in unrighteousness.” Isaiah 66:3, 4 ; 2 Thessalonians 2:11, 10, 12 . 8T 249"
"Therefore will I number you to the sword, and ye shall all bow down to the slaughter: because when I called, ye did not answer; when I spake, ye did not hear; but did evil before mine eyes, and did choose that wherein I delighted not."
The EGW passage quotes Isaiah 66:3,4 and Isaiah 65:12. The provided verse is Isaiah 65:12, which is directly quoted.
"And for this cause God shall send them strong delusion, that they should believe a lie:"
EGW directly quotes 2 Thessalonians 2:11.
"The powers from beneath are stirred with deep intensity. War and bloodshed are the result. The moral atmosphere is poisoned with cruel, horrible doings. The spirit of strife is spreading; it abounds in every place. Many souls are being taken possession of by the spirit of fraud, or underhand dealing. Many will depart from the faith, giving heed to seducing spirits and doctrines of devils. They do not discern what spirit has taken possession of them. 8T 249.1"
"Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;"
The EGW passage directly mentions 'depart from the faith, giving heed to seducing spirits and doctrines of devils,' which is a clear and direct allusion to 1 Timothy 4:1.
"The heavenly Teacher inquired: “What stronger delusion can beguile the mind than the pretense that you are building on the right foundation and that God accepts your works, when in reality you are working out many things according to worldly policy and are sinning against Jehovah? Oh, it is a great deception, a fascinating delusion, that takes possession of minds when men who have once known the truth, mistake the form of godliness for the spirit and power thereof; when they suppose that they are rich and increased with goods and in need of nothing, while in reality they are in need of everything.” 8T 249.3"
"Having a form of godliness, but denying the power thereof: from such turn away."
EGW's passage echoes the idea of having a form of godliness but lacking the power thereof, which is the core concept of 2 Timothy 3:5.
"Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked:"
EGW's passage directly alludes to the Laodicean church's self-deception described in Revelation 3:17, particularly the phrase "rich and increased with goods, and in need of nothing."
