How do you figure that? National Israel is being brought back together ever since 1948
Jesus is concerned with spiritual fruit, i.e. faith.
The fact that Jews have formed a nation they call Israel does not negate the fact that the kingdom was taken from national Israel and given to another nation.
National Israel will never bear fruit again, we look to the new nation to bear fruit.
Do you know what nation it is that bears fruit?
What hubris.
Romans 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
Romans 11:28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 29 for the gifts and the calling of God are irrevocable.
What did you say about God revoking the promises to Israel?
The kingdom remains open to all who believe and the covenant made with Abraham has not been voided.
This story about the fig tree is most likely Mark's attempt to clarify Jesus' actions in the Temple.
He uses a sandwich technique here and in other areas by placing the initial curse on the tree before Jesus' actions in the Temple and then finding it withered afterwards.
The destruction of the tree is tied to the actions in the Temple and most likely indicates not the rejection of the nation but prophesies the destruction of the Temple in 70 AD.
