The Torah states, “G-D is not a man, …. nor the son of man” and “you saw no form or likeness” and Malachi 3.6 states “G-D does not change” – that is, G-D cannot become a human being or die!!!
The Prophet Isaiah states, ” Thus saith the L-RD, the King of Israel, And his Redeemer the L-RD of Hosts: I am the first, and I am the last, And beside Me there is no God.”
The Torah is quite specific: If a prophet prophesies falsely they are to be put to death!
So how can we tell whether a prophet is a “true prophet” (nevi emet) or a false prophet (nevi sheker)? Our passage (Deuteronomy 18:21-22) gives us an answer: “And should you ask yourselves, ‘How can we know that the oracle was not spoken by the Eternal?’ If the prophet speaks in the name of the Eternal and the oracle does not come true, that oracle was not spoken by the Eternal; the prophet has uttered it presumptuously; do not stand in dread of that person.”
That piece of advice is helpful in relation to those self-proclaimed prophets who warn that the world will end tomorrow or perhaps next week or next year. This kind of prophecy has a cut-off date. If it doesn’t happen, then the person is not a real prophet.
Jesus falsely prophesied that the son of man would establish the kingdom on earth within the life-time of Jesus’ disciples.
Matthew 16:28, “Truly I say to you, there are some of those who are standing here who shall not taste death until they see the Son of Man coming in His kingdom.” Luke 9:27 “But I tell you of a truth, there be some standing here, which shall not taste of death, till they see the kingdom of G-D.”
The son of man is Ezekiel (as Ezekiel 29.1-2 emphatically states).
Because Jesus appropriated the title “son of man” to himself and he made a prophesy about the restoration of the kingdom of Israel which never came to pass, he is classified as a nevi sheker (false prophet)!
