24:30. And then shall appear the sign of the Son of man in heaven. And then shall all tribes of the earth mourn: and they shall see the Son of man coming in the clouds of heaven with much power and majesty.

The sign, etc… The cross of Christ.

24:31. And he shall send his angels with a trumpet and a great voice: and they shall gather together his elect from the four winds, from the farthest parts of the heavens to the utmost bounds of them.

24:32. And from the fig tree learn a parable: When the branch thereof is now tender and the leaves come forth, you know that summer is nigh.

24:33. So you also, when you shall see all these things, know ye that it is nigh, even at the doors.

24:34. Amen I say to you that this generation shall not pass till all these things be done.

24:35. Heaven and earth shall pass: but my words shall not pass.

Shall pass… Because they shall be changed at the end of the world into a new heaven and new earth.

24:36. But of that day and hour no one knoweth: no, not the angels of heaven, but the Father alone.

24:37. And as in the days of Noe, so shall also the coming of the Son of man be.
