As already mentioned, the fig tree is a natural example of the nation of Israel. Jesus was revealing that when Israel was restored to her own land and began to "blossom" again as a nation, the time of the return of the King was near. (This event has already happened...Israel has been restored to her own land as a nation!)
Sinasabi ni Jesus na kapag ang Israel ay nabalik na sa kanyang sariling lupain, at magumpisa itong “bumukadkad” na muli bilang isang bansa, nalalapit na ang pagbabalik ng Hari. (Naganap na ang pangyayaring ito…Nabalik na ang Israel sa sarili niyang bayan at natatag na bilang isang bansa!)
