"But the people of God will not be misled. The teachings of this false Christ are not in accordance with the Scriptures. His blessing is pronounced upon the worshipers of the beast and his image, the very class upon whom the Bible declares that God's unmingled wrath shall be poured out. GC 625.1"
"And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:"
The EGW passage explicitly connects the false Christ's blessing of the worshipers of the beast with the Bible's declaration of God's wrath upon them, directly alluding to Revelation 14:9-10.
"And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ; and shall deceive many."
Both passages warn against deception by those claiming to be Christ. While not a direct quote, the theme of deception and false Christs is clearly present in both.
"And, furthermore, Satan is not permitted to counterfeit the manner of Christ's advent. The Saviour has warned His people against deception upon this point, and has clearly foretold the manner of His second coming. “There shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.... Wherefore if they shall say unto you, Behold, He is in the desert; go not forth; behold, He is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.” Matthew 24:24-27, 31 ; 25:31 ; Revelation 1:7 ; 1 Thessalonians 4:16, 17 . This coming there is no possibility of counterfeiting. It will be universally known—witnessed by the whole world. GC 625.2"
"For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before. Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be."
Ellen White directly references Matthew 24:24-27 in this passage.
"Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen."
Ellen White directly references Revelation 1:7 in this passage.
"Only those who have been diligent students of the Scriptures and who have received the love of the truth will be shielded from the powerful delusion that takes the world captive. By the Bible testimony these will detect the deceiver in his disguise. To all the testing time will come. By the sifting of temptation the genuine Christian will be revealed. Are the people of God now so firmly established upon His word that they would not yield to the evidence of their senses? Would they, in such a crisis, cling to the Bible and the Bible only? Satan will, if possible, prevent them from obtaining a preparation to stand in that day. He will so arrange affairs as to hedge up their way, entangle them with earthly treasures, cause them to carry a heavy, wearisome burden, that their hearts may be overcharged with the cares of this life and the day of trial may come upon them as a thief. GC 625.3"
"Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free."
The EGW passage emphasizes the importance of knowing and adhering to the Scriptures to avoid deception, which aligns with the principle in John 8:31-32 that knowing the truth (God's word) leads to freedom (from deception).
"Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father."
Both passages emphasize the importance of abiding in what has been heard from the beginning (the truth/scriptures) to remain in the Son and Father, and to be shielded from delusion.
