"For the coming of the Son of Man will be just like the days of Noah... For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and they did not understand until the flood came and took them all away, so will the coming of the Son of Man be. Then there will be two men in the field, one will be taken and one will be left.…Two women will be grinding at the mill, one will be taken and one will be left.
Therefore be on the alert, for you do not know which day your Lord is coming."
Matthew 24, 37-42

Jesus spoke to them again in parables, saying: "The kingdom of heaven may be compared to a King who gave a wedding feast for his son. And he sent out his slaves to call those who had been invited to the wedding feast, and they were unwilling to come.
Again he sent out other slaves saying, 'Tell those who have been invited, behold, I have prepared my dinner; my oxen and my fattened livestock are all butchered and everything is ready; come to the wedding feast.' But they paid no attention and went their way, one to his own farm, another to his business, and the rest seized his slaves and mistreated them and killed them.
But the king was enraged, and he sent his armies and destroyed those murderers and set their city on fire.
Then he said to his slaves, 'The wedding is ready, but those who were invited were not worthy. Go therefore to the main highways, and as many as you find there, invite to the wedding feast.' Those slaves went out into the streets and gathered together all they found, both evil and good; and the wedding hall was filled with dinner guests .But when the king came in to look over the dinner guests, he saw a man there who was not dressed in wedding clothes, and he said to him, 'Friend, how did you come in here without wedding clothes?' And the man was speechless."Then the king said to the servants, 'Bind him hand and foot, and throw him into the outer darkness; in that place there will be weeping and gnashing of teeth.…"For many are called, but few are chosen.""
Matthew 22,1-14
Then the angel said to me, "Write this: Blessed are those who are invited to the wedding supper of the Lamb!" And he added, "These are the true words of God."
Revelation 19,9
