Are you referring to the same Jesus who was alive before Abraham was born? The Jesus who spoke to Abraham?
"Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am." (John 8:58 KJV)
If Jesus was alive before Abraham, how can he be a Jew? Abraham was not a Jew?
>>>your Messiah may come, but it wont be the same guy sitting on the right hand of the Father in the end<<<
Jesus is already sitting on the right hand of the Father in heaven, on the throne of David. This is something else about Jesus you may not be aware of: Jesus is the Father. Recall this statement Jesus made to Philip:
"Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?" (John 14:9 KJV)
And how about this one:
"I and my Father are one." (John 10:30 KJV)
Isaiah also said he was the Father:
"For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace." (Isa 9:6 KJV)
