Luke 21:29-33

Then he gave them this illustration: “Notice the fig tree, or any other tree. When the leaves come out, you know without being told that summer is near. In the same way, when you see all these things taking place, you can know that the Kingdom of God is near. I tell you the truth, this generation will not pass from the scene until all these things have taken place. Heaven and earth will disappear, but my words will never disappear.
