2 Timothy 3:1 KJV
This know also, that in the last days perilous times shall come.
Luke 21:25-28, 33-36 NKJV
“And there will be signs in the sun, in the moon, and in the stars; and on the earth distress of nations, with perplexity, the sea and the waves roaring;
 men’s hearts failing them from fear and the expectation of those things which are coming on the earth, 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.
 Now when these things begin to happen, look up and lift up your heads, because your redemption draws near.”
 Heaven and earth will pass away, but My words will by no means pass away.
 “But take heed to yourselves, lest your hearts be weighed down with carousing, drunkenness, and cares of this life, and that Day come on you unexpectedly.
 For it will come as a snare on all those who dwell on the face of the whole earth.
 Watch therefore, and pray always that you may be counted worthy to escape all these things that will come to pass, and to stand before the Son of Man.”
