There were a few rabbis who thought some of the messianic verses in the Hebrew Bible referred to someone more than a mere human political leader who would restore Israel to its true glory. Jesus came to demonstrate that he was the messiah based on a different viewpoint of what the messiah was to be. Only by accepting the claims Jesus made about himself and who he was, can anyone understand such concepts correctly. In other words, the Jewish concept of messiah at the time of Jesus had become corrupted, if it was ever properly understood at all.
You can't prove this to anyone who won't believe the teachings of the Christian apostles regarding Jesus.
According to Jesus His message was the same as that of the prophets from Moses to Himself. Note, the reaction from Israel was always the same.
Matthew 21
33“Listen to another parable. There was a landowner who PLANTED A VINEYARD AND PUT A WALL AROUND IT AND DUG A WINE PRESS IN IT, AND BUILT A TOWER, and rented it out to vine-growers and went on a journey.
34“When the harvest time approached, he sent his slaves to the vine-growers to receive his produce.
35“The vine-growers took his slaves and beat one, and killed another, and stoned a third.
36“Again he sent another group of slaves larger than the first; and they did the same thing to them.
37“But afterward he sent his son to them, saying, ‘They will respect my son.’
38“But when the vine-growers saw the son, they said among themselves, ‘This is the heir; come, let us kill him and seize his inheritance.’
39“They took him, and threw him out of the vineyard and killed him.
40“Therefore when the owner of the vineyard comes, what will he do to those vine-growers?”
41They said to Him, “He will bring those wretches to a wretched end, and will rent out the vineyard to other vine-growers who will pay him the proceeds at the proper seasons.”
42Jesus said to them, “Did you never read in the Scriptures,
‘THE STONE WHICH THE BUILDERS REJECTED,
THIS BECAME THE CHIEF CORNER stone;
THIS CAME ABOUT FROM THE LORD,
AND IT IS MARVELOUS IN OUR EYES’?
The Message
Don´t be like the world, working for temporary benefits that rusted and spoiled. Using human means.
Be like Abraham, who learned to depend on God for eternal life, kingdom living, with food, clothing, and even security, preservation of life added to him. The prophets, including Jesus said many things, but please separate out the central message:
Matthew 6
33"But seek first His kingdom and His righteousness, and all these things will be added to you.
The Reaction
If a group received the message, they were divided, father turned against children, brother against sister, and whoever believed was persecuted. Joshua and Caleb believed and were almost stoned. Note, Israel as a group never believed, they always killed the prophets.
Reflection on why the Message was Rejected
Being born from above was to repent, meta noia, change your mind that life was about filling hunger which required filling when one hungered again, working for temporary benefits and in the process exploiting others for self interest, change it to a mind set that life was about subduing creation, completing , perfecting what God started, the task given to Adam, possible only when God was with you. A horse is fulfilled only when it is harnessed, bridled. Creation is only complete, when it is brought under control. Man is only perfected when he abandons self interest and follows Christ. Being born from above is a noble change, above having that connotation, as opposed to below. It's also being born again, a transformation.
However, anyone will tell you it's impractical. Can God really feed you like He does the birds of the air? No wonder Israel rejected it. No wonder father turns against son, brother against sibling.
Choose today whom you will serve.
Mammon, for benefits that rust and perish
Or
God, for permanent benefits.
Also
Be compliant with the Mosaic Covenant for eternal life
Or
Be compliant with the New Covenant to be a blessing to the world in multiple ways.
Matthew 19
16And someone came to Him and said, “Teacher, what good thing shall I do that I may obtain eternal life?”
17And He said to him, “Why are you asking Me about what is good? There is
only One who is good; but if you wish to enter into life, keep the commandments.”
18Then he said to Him, “Which ones?” And Jesus said, “YOU SHALL NOT COMMIT MURDER; YOU SHALL NOT COMMIT ADULTERY; YOU SHALL NOT STEAL; YOU SHALL NOT BEAR FALSE WITNESS;
19HONOR YOUR FATHER AND MOTHER; and YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.”
20The young man said to Him, “All these things I have kept; what am I still lacking?”
21Jesus said to him, “If you wish to be complete, go
and sell your possessions and give to
the poor, and you will have treasure in heaven; and come, follow Me.”
Matthew 10
41"He who receives a prophet in the name of a prophet shall receive a prophet's reward; and he who receives a righteous man in the name of a righteous man shall receive a righteous man's reward.
