"“By the word of God ... the world that then was, being overflowed with water, perished: but the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.” 2 Peter 3:5-7 . Another storm is coming. The earth will again be swept by the desolating wrath of God, and sin and sinners will be destroyed. PP 101.1"
"For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: Whereby the world that then was, being overflowed with water, perished: But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men."
Ellen White directly references 2 Peter 3:5-7 in this passage.
The sins that called for vengeance upon the antediluvian world exist today. The fear of God is banished from the hearts of men, and His law is treated with indifference and contempt. The intense worldliness of that generation is equaled by that of the generation now living. Said Christ, “As in the days that were before the Flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark, and knew not until the Flood came, and took them all away; so shall also the coming of the Son of man be.” Matthew 24:38, 39 . God did not condemn the antediluvians for eating and drinking; He had given them the fruits of the earth in great abundance to supply their physical wants. Their sin consisted in taking these gifts without gratitude to the Giver, and debasing themselves by indulging appetite without restraint. It was lawful for them to marry. Marriage was in God's order; it was one of the first institutions which He established. He gave special …
"But as the days of Noe were, so shall also the coming of the Son of man be."
EGW directly quotes Matthew 24:38-39, making this an explicit allusion. She then expands on the meaning of the passage in the context of the antediluvian world.
"having once escaped control, will fill the earth with woe and desolation. The picture which Inspiration has given of the antediluvian world represents too truly the condition to which modern society is fast hastening. Even now, in the present century, and in professedly Christian lands, there are crimes daily perpetrated as black and terrible as those for which the old-world sinners were destroyed. PP 101.3"
"But as the days of Noe were, so shall also the coming of the Son of man be."
EGW draws a parallel between the wickedness of the antediluvian world and the state of modern society, similar to Jesus' comparison in Matthew 24:37.
