Luke 21:25-30

And there shall be signs in sun and moon and stars, and upon the earth distress of nations in perplexity at the roar of the sea and rolling waves, men ready to die through fear and expectation of what is coming on the habitable earth, 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 draws nigh. And he spoke a parable to them: Behold the fig-tree and all the trees; when they already sprout, ye know of your own selves, on looking at them, that already the summer is near.
