Jesus said to his disciples:
“There will be signs in the sun, the moon, and the stars, 
and on earth nations will be in dismay, 
perplexed by the roaring of the sea and the waves.
People will die of fright 
in anticipation of what is coming upon the world, 
for the powers of the heavens will be shaken.
And then they will see the Son of Man 
coming in a cloud with power and great glory.
But when these signs begin to happen, 
stand erect and raise your heads 
because your redemption is at hand.

“Beware that your hearts do not become drowsy 
from carousing and drunkenness 
and the anxieties of daily life, 
and that day catch you by surprise like a trap.
For that day will assault everyone
who lives on the face of the earth.
Be vigilant at all times 
and pray that you have the strength 
to escape the tribulations that are imminent 
and to stand before the Son of Man.” (Lk 21:25-28, 34-36)
