Even though we announced in 1935 that the Great Crowd, unnumbered in size, will come out of the Great Tribulation as survivors, the Great Crowd as yet to be formed. (Rev 7:9) Those who become members of the Great Crowd will soon develop 'a new and living hope' of surviving the Great Tribulation after it begins and not before. This happens after Jesus turns his attention to gathering the Great Crowd through his separation work.
Most likely this event parallels with the event of the message changing from declaring the Good News of Salvation to the declaration of everlasting destruction. This message will send Satan and his hordes into a tizzy. When delivering such a strong and denunciating message, it will take faith and courage to carry out this life saving assignment. Jehovah could easily send an angel to these households and they would immediately fall into death as they drop to the floor. But Jehovah is allowing You to be apart of the Vindication His Wonderful Name. So keep in mind, all those times when the householders tried to impend You from declaring the Good News of Salvation to them then to others. Keep the faith and be strong as this Prophecy unfolds and lift your heads for Your Salvation is near: "This takes into account that it is righteous on God’s part to repay tribulation to those who make tribulation for you. But you who suffer tribulation will be given relief along with us at the revelation of the Lord Jesus from heaven with his powerful angels in a flaming fire, as he brings vengeance on those who do not know God and those who do not obey the good news about our Lord Jesus. These very ones will undergo the judicial punishment of everlasting destruction from before the Lord and from the glory of his strength," (2 Thessalonians 6-9) Jehovah is a God of Order, "let all things take place decently and by arrangement." (1 Corinthians 14:40) It will be chaotic time for the ungodly who receive these messages, but like a nice cool drink, for those who are still thirsty for righteousness. "Happy are those hungering and thirsting for righteousness, since they will be filled. " (Matthew 5:6)
those hungering and thirsting for righteousness: That is, those who long to see corruption and injustice replaced with God’s standards of right and wrong; they strive to conform to those standards. Footnotes: those 'satisfied':
55 Come, all you thirsty ones, come to the water!You with no money, come, buy and eat!Yes, come, buy wine and milk without money and without cost.
21 “Happy are you who hunger now, for you will be filled.“Happy are you who weep now, for you will laugh.
35 Jesus said to them: “I am the bread of life. Whoever comes to me will not get hungry at all, and whoever exercises faith in me will never get thirsty at all.
Revelation 7:16, 17
16 They will hunger no more nor thirst anymore, neither will the sun beat down on them nor any scorching heat, 17 because the Lamb, who is in the midst of the throne, will shepherd them and will guide them to springs of waters of life. And God will wipe out every tear from their eyes.”
