Luke 21:25-28

And there shall be signs in sun and moon and stars; and upon the earth distress of nations, in perplexity for the roaring of the sea and the billows; men fainting for fear, and for expectation of the things which are coming on the world: for the powers of the heavens shall be shaken. And then shall they see the Son of man coming in a cloud with power and great glory. But when these things begin to come to pass, look up, and lift up your heads; because your redemption draweth nigh.
