Luke 21:29-33

29Then He told them a parable: “Look at the fig tree and all the trees;

30as soon as they put out leaves, you see it and know for yourselves that summer is near.

31So you too, when you see these things happening, know [without any doubt] that the kingdom of God is near.

32I assure you and most solemnly say to you, this generation [those living at that definite period of time preceding the second coming] will not pass away until everything takes place.

33Heaven and earth will pass away, but My words will not pass away.
