What in the World are We Going to Do?

Luke 21:25-28 
(25) And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;  (26)  Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.  (27)  And then shall they see the Son of man coming in a cloud with power and great glory.  (28)  And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.
