Luke 21:27-28 and 31-33

 "'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.'"

 "So you also, when you see these things happening, know that the kingdom of God is near.'"

 "'Assuredly, I say to you, this generation will by no means pass away till all things take place.'"

 "'Heaven and earth will pass away, but My words will by no means pass away.'"
