Jesus says ³learn a lesson from the fig tree.² This does not mean interpret what the fig tree is.

Matt 24:32 When you see the leaves sprouting, you know that summer is coming soon. In the same way, when you see the signs which Jesus has been talking about, you know the next events that you are expecting are near. What events were they expecting? The second coming (Matt 24:3)

vs. 34 This generation is not the disciples. It is the generation that sees the signs. What signs? The events of the Tribulation. So, the generation that sees the events of the Tribulation will see the second coming of Christ.

Verses 34 and 35 give us the idea of imminency (it will take place soon - for that generation) and inerrancy (it is sure to happen.)

Heaven and earth will pass away after the Millenium. Then a new heaven and earth will be created..

After Jesus tells the parable of the fig tree, He gives several brief parables to show what the response one should have when he sees the signs.
