Later, Jesus sat on the Mount of Olives. His disciples came to him privately and said, “Tell us, when will all this happen? What sign will signal your return and the end of the world?”
And then at last, the sign that the Son of Man is coming will appear in the heavens, and there will be deep mourning among all the peoples of the earth. And they will see the Son of Man coming on the clouds of heaven with power and great glory.
If that had been necessary, Christ would have had to die again and again, ever since the world began. But now, once for all time, he has appeared at the end of the age to remove sin by his own death as a sacrifice.
