When he was sitting on the Mount of Olives, the disciples came to him privately, saying, “Tell us, when will this be, and what will be the sign of your coming and of the end of the age?”
Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see ‘the Son of Man coming on the clouds of heaven’ with power and great glory.
But understand this: if the owner of the house had known in what part of the night the thief was coming, he would have stayed awake and would not have let his house be broken into.
for then he would have had to suffer again and again since the foundation of the world. But as it is, he has appeared once for all at the end of the age to remove sin by the sacrifice of himself.
