The real church will arise. It will look different. I can't tell you precisely what it will look like, but it's not yet defined. It's organic. Rising out of burning hearts of Love for God and his people.
Many will mourn and wail for it's death..but the new rising out of the rubble will be powerful.
It makes me think of this from the Revelation 18:
Lament Over Fallen Babylon18 After this I saw another angel coming down from heaven. He had great authority, and the earth was illuminated by his splendor. 2 With a mighty voice he shouted:“‘Fallen! Fallen is Babylon the Great!’
She has become a dwelling for demons
and a haunt for every impure spirit,
a haunt for every unclean bird,
a haunt for every unclean and detestable animal.
3 For all the nations have drunk
the maddening wine of her adulteries.
The kings of the earth committed adultery with her,
and the merchants of the earth grew rich from her excessive luxuries.”
Warning to Escape Babylon’s Judgment4 Then I heard another voice from heaven say:
“‘Come out of her, my people,’
so that you will not share in her sins,
so that you will not receive any of her plagues;
5 for her sins are piled up to heaven,
and God has remembered her crimes.
6 Give back to her as she has given;
pay her back double for what she has done.
Pour her a double portion from her own cup.
7 Give her as much torment and grief
as the glory and luxury she gave herself.
In her heart she boasts,
‘I sit enthroned as queen.
I am not a widow;
I will never mourn.’
8 Therefore in one day her plagues will overtake her:
death, mourning and famine.
She will be consumed by fire,
for mighty is the Lord God who judges her.
