Also do not forget what Jesus says later in both Matthew and Mark... several chapters after the cursing of the fig tree and the parable of the fig tree Jesus says this:
"Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see these things happening, you know that it is near, right at the door. I tell you the truth, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my workds will never pass away." - Matthew 24:32-35 and Mark 13:28-31.
Jesus is speaking here just after relating a series of warnings about the end times and in fact the since the fig tree represents the NATION (tree) of ISRAEL (fig) it is feasible to suggest that this is a direct prophesy about the coming of the Tribulation.
I'm not the kind of person who goes around prognosticating and ranting about the end of the world and the Bible clearly says that "the day of the Lord will come like a thief" (2 Peter 3:10) so I'm not trying to predict the end but I do think that it is fascinating to see how this correllates with the withering of the nation of Israel about AD 70 and its subsequent rebirth in AD 1948.
I've read that the Bible maintians that a generation lasts 40 years and begins in the 20th year and ends in the 60th, putting the coming of Christ some time in 2008 if you do the math that way. But generation could also mean RACE in which case there is no math to be done. If this is the prophesised generation of the fig tree then we may see these things fulfilled very soon. Perhaps not though.
The point is to be prepared and always have your heart in the right state and never waver in doing the work God has put you here to do.
