I believe that was what Jesus was referring to about learning the parable of the fig tree.
Except he didn't only speak of that one tree. What about the other ones?
Luk 21:29 And he spake to them a parable; Behold the fig tree,
and all the trees;
Luk 21:30 When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
Luk 21:31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
Clearly this has nothing to do with 1948. He is speaking of all trees, when they shoot forth then summer is near which is the kingdom of God ie: the second coming. What he is saying is there are signs that we will see that will tell us when the second coming is near. It has nothing at all to do with Israel, not in 1948, 1967 or any year. It's not about only the fig tree. It's about how all trees behave when spring begins. They begin to come back to life and start growing and sprouting! It's a wonderful time of year! We are currently in the winter prophetically. We are looking for the signs of sprouting which is progression but progression of end times events. We need to be looking for the Revelation 13 events of two beasts and global changes.
