Jews for Jesus, Cult or Heretics ?

As a Christian, i find it perplexing that among Religious
Judaism the concept of being a follower of Y'Shua, is an
anathema. It is more palatable for a Jew, to happen to,
convert to some other Religion.

If i am not mistaken Y'Shua himself was a Jewish Rabbi.
Time and time again, the term the Pharisees refered to
Y'shua was Rabbi (Teacher).

It was Y'Shua who said

34“O Jerusalem, Jerusalem, the city that kills the prophets 
and stones God’s messengers! How often I have wanted to
gather your children together as a hen protects her chicks 
beneath her wings, but you wouldn’t let me. 35And now, 
look, your house is abandoned. And you will never see me
again until you say,
‘Blessings on the one who comes in the name of the Lord!’
b” ~ Luke 13:34

My belated Uncle was a Jewish Believer in Jesus.  A
Jewish remnant hiding among Muslims. There are no
Synagogue's in Malaysia nor could he have gone to a
local Rabbi to maintain his ties. There are simply no
Rabbi's in Malaysia. So, why did he choose Y'Shua ?
He had been really ill for sometime towards the end of
his life. He believed in his last breath that Y'shua his
Messiah was going to take him home.
