All the nations of the earth will mourn.

After that time of suffering,

the sun will be darkened, and the moon will not give its light,

the stars will fall, and the heavenly bodies will be shaken.

Then the sign of Jesus' coming will appear in the sky,

and all the nations of the earth will mourn.

They will see Jesus coming on a cloud with power and great glory.

Jesus will send his angels with a loud trumpet sound,

and they will gather his chosen ones from the four winds,

from one end of heaven to the other

(Matthew 24:29-31, Korean Modern Bible).
