Where do you get this definition or description of prophesying from the Bible?
Every one who claimed he was a prophet, a person speaking in place of God, needed to prove he was a prophet by doing a miraculous sign or have his prediction become true:
Exodus 4
4But the LORD said to Moses, “Stretch out your hand and grasp
it by its tail”—so he stretched out his hand and caught it, and it became a staff in his hand—
5“that they may believe that the LORD, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has reappeared to you.”
Deuteronomy 18
22“When a prophet speaks in the name of the LORD, if the thing does not come about or come true, that is the thing which the LORD has not spoken.
Every prophet had to have a message which did not lead Israel away from obeying God's law to prove he was acceptable.
Deuteronomy 13
1“If a prophet or a dreamer of dreams arises among you and gives you a sign or a wonder,
2and the sign or the wonder comes true, concerning which he spoke to you, saying, ‘Let us go after other gods (whom you have not known) and let us serve them,’
3you shall not listen to the words of that prophet or that dreamer of dreams; for the LORD your God is testing you to find out if you love the LORD your God with all your heart and with all your soul.
Again, they said, 'John did no miracle.' But he was still a prophet. Lots of prophets di d miracles. But we do not know if a lot of the Old Testament prophets ever did any miracles.
The test of a prophet is not to have unfulfilled prophesies. John did no miracles but everything he said about Jesus was fulfilled:
John 10
41Many came to him and began to say, “John performed no miraculous sign, but everything John said about this man was true!” 42Many believed in Him there.
God doesn't owe us miracles. He confirms His word if He chooses. If He sends a prophet without confirming through a sign, that is up to Him. Jesus refused to give a sign to a wicked and adulterous generation except for the sign of the prophet Jonah. He wasn't obligated to give them a sign.
If good men are willing to give proof that they are able to help you, is God not as good? He readily gave Moses the ability to do miracles:
Exodus 4
1Then Moses said, “What if they will not believe me or listen to what I say? For they may say, ‘The LORD has not appeared to you.’”
2The LORD said to him, “What is that in your hand?” And he said, “A staff.”
3Then He said, “Throw it on the ground.” So he threw it on the ground, and it became a serpent;
The Jews wanted to trip Jesus, which is why he refused to give them any more signs. The sign of Jonah did two things. It was for an adulterous Israel, which was chasing after foreign Gods. It raised up the Gentile, who defeated and took Israel out of Jerusalem, removing her position as the people of God. They could not function, could not sing the Lord's song in a strange land. 'Jew' means one who praises God.
They were probably wanting the fulfilled prediction type sign, mentioned in Deuteronomy, as opposed to the signs Jesus was doing left and right of healing, multiplying food, etc.
Quote
But Moses was given another sign--when he and the people returned to Mount Sinai after the exodus they would worship at the mountain. That was a sign that would confirm that God had done it, but it was not a sign to convince them to go to the mountain to worship. Once they got there they would be assured that God had done just as He had promised.
These Pharisees and teachers clearly wanted the former type, a sign to convince them to believe. But they were dishonest and Jesus saw right through them. They had just seen a spectacular sign, the casting out of the demon so that the man regained his abilities, and instead of believing they accused Him of doing it by Beelzebub. They were not interested in a sign, only in trying to discredit Jesus.

Here you are right. They wanted a commitment from Jesus, a prediction, that they would be confirmed as God's people, probably by a statement saying Rome would be evicted and Jews would worship freely in the Temple. Instead the sign of Jonah predicted the scattering of Israel.
John preached in some remote areas. John may have interpreted law for city dwellers. Okay. But so do plenty of judges who live in the city or who started working in cities when American society became more rural. t hat doesn't make them prophets. Priests in John's day who judged cases related to the temple may have applied the law for city-dwellers. That does not mean they were all prophets.
John the Baptist drank water. Does that mean everyone who drinks water is a prophet? Is anyone who eats locust a prophet?
My point is that prophecy need not be added to Canon.
Many in His audience may not have recognized this. Many prophets predicted future events.
The point is that John's predictions came true. That is why people decided to take his advice and followed Jesus.
You don't have to try so hard. The Bible alludes to a large number of prophecies and revelations that were not included in the canon.
Then why do you see a problem in the fact that modern prophecies are not added after the book of revelations?
It's great that they loved people. But that didn't make them prophets.
Yup. Paul should have just told Agabus that he was Satan and that he needed to get behind him.
That was sarcasm.
