St Luke 21:25-27

And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, by reason of the confusion of the roaring of the sea and of the waves; Men withering away for fear, and expectation of what shall come upon the whole world. For the powers of heaven shall be moved; And then they shall see the Son of man coming in a cloud, with great power and majesty.
