"In the time of trial before us God's pledge of security will be placed upon those who have kept the word of His patience. Christ will say to His faithful ones: “Come, My people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast.” Isaiah 26:20 . The Lion of Judah, so terrible to the rejectors of His grace, will be the Lamb of God to the obedient and faithful. The pillar of cloud which speaks wrath and terror to the transgressor of God's law is light and mercy and deliverance to those who have kept His commandments. The arm strong to smite the rebellious will be strong to deliver the loyal. Every faithful one will surely be gathered. “He shall send His angels with a great sound of a trumpet, and they shall gather together His elect from the four winds, from one end of heaven to the other.” Matthew 24:31 . 6T 404.2"
"Come, my people, enter thou into thy chambers, and shut thy doors about thee: hide thyself as it were for a little moment, until the indignation be overpast."
Ellen White directly references Isaiah 26:20 in this passage.
"And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other."
Ellen White directly references Matthew 24:31 in this passage.
"indifference. Let not the destiny of your soul hang upon an uncertainty. Know that you are fully on the Lord's side. Let the inquiry go forth from sincere hearts and trembling lips, “Who shall be able to stand?” Have you, in these last precious hours of probation, been putting the very best material into your character building? Have you been purifying your souls from every stain? Have you followed the light? Have you works corresponding to your profession of faith? 6T 404.3"
"For the great day of his wrath is come; and who shall be able to stand?"
EGW directly quotes Revelation 6:17, making it an explicit allusion rather than a thematic parallel. The confidence is increased due to the direct quotation.
