Yes a flood washes away things, so the comparison to the time of Noah and being taken away to destruction is apropos. Noah is protected in the ark and remains to inherit the earth, all others are killed, Noah found favor with God and was a preacher of righteousness; do the right things God wants you to do and you are saved from His wrath. This world and all them the live therein are on borrowed time being condemned already as they are the sons of disobedience.
Scripture often is designed to form word pictures in your mind.
Lot escaping from the cities of the plain with angelic assistance is analogous to Christ coming to gather His people to safety and destroy all the unbelieving and wicked with fire from the Lord out of heaven, shows what happens to the wicked, they are burned up in hellfire, while righteous Lot was divinely preserved. Jesus tells us to remember Lot's Wife though as a warning! Abraham looked at the destruction from afar, so just looking at it was not the problem. Lot's wife looked back and anyone looking back Jesus said is not fit for the kingdom of God.
Luke 9:62
But Jesus said to him, “No one, having put his hand to the plow, and looking back, is fit for the kingdom of God.”
Luke 17
28 Likewise as it was also in the days of Lot: They ate, they drank, they bought, they sold, they planted, they built; 29 but on the day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed
them all. 30 Even so will it be in the day when the Son of Man is revealed.
31 “In that day, he who is on the housetop, and his [
i]goods
are in the house, let him not come down to take them away. And likewise the one who is in the field, let him not turn back. 32 Remember Lot’s wife. 33 Whoever seeks to save his life will lose it, and whoever loses his life will preserve it. 34 I tell you, in that night there will be two [
j]
men in one bed: the one will be taken and the other will be left. 35 Two
women will be grinding together: the one will be taken and the other left. 36 [
k]Two
men will be in the field: the one will be taken and the other left.”
37 And they answered and said to Him, “Where, Lord?”
So He said to them, “Wherever the body is, there the eagles will be gathered together.”
God preserves the lives of His saints, the angels could not carry out the heaven ordered destruction until Lot was safe.
Genesis 19
18 Then Lot said to them, “Please, no, my lords! 19 Indeed now, your servant has found favor in your sight, and you have increased your mercy which you have shown me by saving my life; but I cannot escape to the mountains, lest some evil overtake me and I die. 20 See now, this city
is near
enough to flee to, and it
is a little one; please let me escape there (
is it not a little one?) and my soul shall live.”
21 And he said to him, “See, I have favored you concerning this thing also, in that I will not overthrow this city for which you have spoken. 22
Hurry, escape there. For I cannot do anything until you arrive there.”
Therefore the name of the city was called [
d]Zoar.
23 The sun had risen upon the earth when Lot entered Zoar. 24 Then the Lord rained brimstone and fire on Sodom and Gomorrah, from the Lord out of the heavens. 25 So He [e]overthrew those cities, all the plain, all the inhabitants of the cities, and what grew on the ground.
26 But his wife looked back behind him, and she became a pillar of salt.
27 And Abraham went early in the morning to the place where he had stood before the Lord. 28
Then he looked toward Sodom and Gomorrah, and toward all the land of the plain; and he saw, and behold, the smoke of the land which went up like the smoke of a furnace. 29 And it came to pass, when God destroyed the cities of the plain, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot had dwelt.
