Yes he did
And how can you tell a false prophet?
They say things will happen. and it does not happen.
No, that is not the proof of a false prophet, that is a superficial understanding and is foolish.
That would be like saying a quarterback who throws an interception needs to be fired.
A false prophet is someone who claims God told him something that turns out to be false.
Second, everyone should realize this accusation of being a false prophet was used against all the legitimate prophets including Jesus.
Whenever I hear that I know this person is a lightweight.
However, if someone gives a vision or dream that has a prophecy and it does prove to be valid, not some vague gypsie scam but a word that seems absurd or impossible, then that is proof, not that they are a prophet of God, but they are a prophet. There have been a number of "prophecies" from the Simpsons that have turned out, the AntiChrist does miracles to deceive the people.
So again, people who see predictive programming and so try and discern what is going to happen from Hollywood is getting involved in poison. Unless you are absolutely clear that the Lord is calling you to do that I would advise to avoid that as a deceitful well.
The proof that a person is of God is that they tell you Jesus Christ is the Son of God, king of Kings, Lord of Lords, He came in the flesh, He died on the cross and His blood washes away your sins, this sacrifice was given freely to all who would receive it.
Balaam was a prophet, what made him "false" was not the prophecies, but the fact that he was motivated by money and would sell you out for money. Judas was a real disciple, a real apostle and a real prophet. But he was false because he was motivated by money and would sell out Jesus for 30 pieces of silver.
