Matthew 3:10 KJV - And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.
Israel had to be fruitful to enter the kingdom on earth, to be a priesthood and reign with Christ on earth.
Jesus spoke similar language to Israel:
Matthew 7:19-20 KJV - Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them.
Israel, not us, would recognize a believer from an unbelieving Jew by their fruit.
