I'll just use the fig tree for example .
The Fig Tree was a teaching in part, from Jeremiah 24. And its about Israel being established ; as a nation in 1948 .
From that point forward, Christ expected the believer, ( those that actually care ) to Watch for the seven signs or seals He taught in Matthew 24 among other places , which are signs and teachings taught throughout the OT prophets, and Christ Himself and His apostles .
But there is more to the parable. For one its symbolic for that which is hidden . It is also a parable for the sin in Eden . When Adam and Eve sinned, thy sewed fig leaves together to cover their privet parts. And the teaching is part of the key of David . Without understanding Christ's parables; Satan takes advantage of ignorant people . This is why we have so many divisions just on the spelling of words, or how its read let alone the difficulty the churches are spreading concerning Christs' parables.
All symbolism used in prophecy is defied in the bible, but you'd have to had actually read the Bible with some recall, to be able to call upon those meanings when you're reading about the Bibles prophecies . Some of its straight forward , but most is not understood without knowing the rest of the Bible. Not going to happen without study and prayer .
