"Elder K knows not of what spirit he is. He is uniting his influence with the dragon host to oppose those who keep the commandments of God, and who have the testimony of Jesus. He has a hard warfare before him. As far as the Sabbath is concerned, he occupies the same position as the Seventh Day Baptists. Separate the Sabbath from the messages, and it loses its power; but when connected with the message of the third angel, a power attends it which convicts unbelievers and infidels, and brings them out with strength to stand, to live, grow, and flourish in the Lord. It is time for God's people in Wisconsin to find their position. “Who will be on the Lord's side?” should be sounded by the faithful, experienced ones in every place. God requires them to come out and cut loose from the various influences which would separate them from one another and from the great platform of truth upon which God is bringing His people. 1T 337.1"
"And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ."
The EGW passage explicitly mentions the dragon opposing those who keep the commandments of God and have the testimony of Jesus, which is a direct allusion to Revelation 12:17. The connection is undeniable and significant.
"and the enemies of our faith have had occasion to reproach Sabbathkeepers. They judge of the tree by its fruits. 1T 337.2"
"Wherefore by their fruits ye shall know them."
EGW directly uses the phrase 'judge of the tree by its fruits,' which is a clear allusion to Matthew 7:20.
"2 Corinthians 4:2 : “But have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man's conscience in the sight of God.” 1T 337.3"
"But have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man’s conscience in the sight of God."
Ellen White directly references 2 Corinthians 4:2 in this passage.
