“There will be signs in sun and moon and stars, and on the earth dismay among nations, in perplexity at the roaring of the sea and the waves, men fainting from fear and the expectation of the things which are coming upon the world; for the powers of the heavens will be shaken. Then they will see the Son of Man coming in a cloud with power and great glory. But when these things begin to take place, straighten up and lift up your heads, because your redemption is drawing near.”
