"The crisis is stealing gradually upon us. The sun shines in the heavens, passing over its usual round, and the heavens still declare the glory of God. Men are still eating and drinking, planting and building, marrying, and giving in marriage. Merchants are still buying and selling. Men are jostling one against another, contending for the highest place. Pleasure lovers are still crowding to theaters, horse races, gambling hells. The highest excitement prevails, yet probation's hour is fast closing, and every case is about to be eternally decided. Satan sees that his time is short. He has set all his agencies at work that men may be deceived, deluded, occupied and entranced, until the day of probation shall be ended, and the door of mercy be forever shut. DA 636.2"
"But as the days of Noe were, so shall also the coming of the Son of man be."
Both passages describe a state of normalcy and unawareness preceding a major event (the flood in Noah's time and the Second Coming).
"Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;"
Both passages describe ordinary activities (eating, drinking, buying, selling, planting, building) occurring before a major event (destruction of Sodom and the Second Coming).
"For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape."
Both passages describe a false sense of security and normalcy preceding sudden destruction. The EGW passage describes people being occupied and entranced, while 1 Thessalonians 5:3 speaks of people saying "Peace and safety".
"Solemnly there come to us down through the centuries the warning words of our Lord from the Mount of Olives: “Take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares.” “Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.” DA 636.3"
"And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares."
EGW directly quotes Luke 21:34.
"Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man."
EGW directly quotes Luke 21:36.
