The God he invites them to seek is not cruel or capricious. Nor is the God he wants them to seek unconcerned for the plight of the people of this world. On the contrary, he is a God who has been more than patient with our disobedience. Jesus explains this by way of a parable. It has been argued that, God is the owner of the vineyard and the vinedresser is Jesus.
Many commentators say that the fig tree is certainly Israel.
This is probable. If you doubt me, read the final chapter of Acts. One more time the owner of the vineyard is giving the fig tree the chance to live up to its potential. Once more the sun is shining and the birds are singing and the gentle rain is falling from heaven. And now there is a practiced hand to carefully cultivate the tree.
