Jesus ... died and rose again and now is alive forever.
I don't believe that. Why would I? The argument for resurrection is that some people say that some other people saw Jesus when he was supposedly dead, and that when a rock was rolled away, there was no body to be seen. There would need to be a suspension f the laws of nature to revivify a body three days dead, and there's no reason to believe that can or has been done.
That would depend which prophecies in the OT you see as describing the Messiah.
It seems like you consider that a subjective process, that one is free to disregard some of the prophecies if he likes.
But yes, my argument is the same as the Jews and all other non-Christians. Here are two treatments I've copied and kept. These are the OT messianic prophecies and where you can find them in scripture. Jesus didn't fulfill these predictions/descriptions (
@metis just posted a similar list):
Criteria for Messiah.
If he fails in one of these, then he cannot be the Messiah.
1. He must be a Jew (Deut 17:15, Num 24:17) - The only condition fulfilled by Jesus.
2. He must be a direct descendant of King David (Isaiah 11:1) through King Solomon (I Proverbs 22:8-10), only if Solomon kept his faith in God Yahweh (II Chronicles 7 :19) which, however, did not keep finally (1 Kings 11:4).
3. The Great Sanhedrin (Great Council) will be restored (Isaiah 1:26)
4. Once he is king, the leaders of other nations will look to him for guidance. (Isaiah 2:4)
5. All the world will worship the One God of Israel (Isaiah 2:17)
6. The Messiah will be a man of the world, an observant Jew with the "fear of God." He won't be divine. (Isaiah 11:2)
7. Evil and tyranny will not be able to stand before his leadership. (Isaiah 11:4)
8. The knowledge of God will fill the world. (Isaiah 11:9)
9. It will attract people from all cultures and nations. (Isaiah 11:10)
10. All the Israelites will return to their homeland. (Isaiah 11:12)
11. There will be no more famine or disease, and death will end. (Isaiah 25:8)
12. All the dead will rise. (Isaiah 26:19)
13. The Jewish people will experience eternal joy and rejoicing. (Isaiah 51:11)
14. He will be a messenger of peace. (Isaiah 52:7)
15. The nations will recognize the mistakes they made in Israel. (Isaiah 52:13-53:5)
16. The people of the world will turn to the Jews for spiritual guidance. (Zechariah 8:23)
17. The ruined cities of Israel will be restored. (Ezekiel 16:55)
18. The weapons of war will be destroyed. (Ezekiel 39:9)
19. The Temple will be rebuilt. (Ezekiel 40)
20. The whole world will serve God together. (Zephaniah 3:9)
21. The Jews will know the Torah (Testament), without study. (Jeremiah 31:33)
22. He will take barren land and make it fruitful and abundant. (Isaiah 51:3, Amos 9:13-15, Ezekiel 36:29-30, Isaiah 11:6-9).
23. Universal worldwide acceptance of the Jewish God and the Jewish religion (Isaiah 2:3 11:10 66:23 Micah 4:2-3 Zechariah 14:9) Zechariah 8:23 "Thus says the Lord of hosts: In those days ten men from the nations of every tongue shall take hold of the robe of a Jewish man, saying, ‘Let us go with you, for we have heard that God is with you”.
=========
1. The Messiah is born of two human parents, as we said. But Jesus, according to Christian theology, was born of the union between a human woman and Gd (as were many other pagan deities, see above) rather than two human parents.
2. The Messiah can trace his lineage through his human biological father, back to King David (
Isaiah 11:1,10;
Jeremiah 23:5;
Ezekiel 34:23-24; 37:21-28;
Jeremiah 30:7-10; 33:14-16;
Hosea 3:4-5). According to Christian theology, Jesus’s father was Gd. Therefore, Jesus’ lineage does not go through his human ‘father’ — Joseph, the husband of Mary.
3. The Messiah traces his lineage only through King Solomon (II Samuel 7:12-17; I Chronicles 22:9-10). But according to
Luke 3:31, Jesus was not a descendant of Solomon, but of Solomon’s half-brother Nathan. Therefore Jesus was not a descendant of King David through King Solomon, and fails this test as well.
4. The Messiah may not be a descendant of Jehoiakim, Jeconiah, or Shealtiel, because this royal line was cursed. (I Chronicles 3:15-17;
Jeremiah 22:18,30). But according to
Matthew 1:11-12 and
Luke 3:27, Jesus was a descendant of Shealtiel.
5. The Messiah is preceded by Elijah the prophet who, together with the Messiah, unifies the family (
Malachi 4:5-6). This is contradicted by Jesus himself (
Matthew 10:34-37).
According to the traditional Jewish definition of the term, the Messiah will make changes in the real world, changes that one can see and perceive and be able to prove, precisely because they take place in the real world. It is for this task that the Messiah has been anointed in the first place, hence the term, messiah — one who is anointed. These perceptible changes include:
6. The Messiah reestablishes the Davidic dynasty through his own children (
Daniel 7:13-14).
But Jesus had no children.
7. The Messiah brings an eternal peace between all nations, all peoples, and all people (
Isaiah 2:2-4;
Micah 4:1-4;
Ezekiel 39:9). Obviously there is no peace. Furthermore, Jesus said that his purpose in coming was to bring a sword, and not peace (see
Matthew 10:34, as referenced above).
8. The Messiah brings about the world-wide conversion of all peoples to Ethical Monotheism (
Jeremiah 31:31-34;
Zechariah 8:23;
Isaiah 11:9;
Zechariah 14:9,16).
But the world remains steeped in idolatry.
9. The Messiah brings about an end to all forms of idolatry (
Zechariah 13:2).
But the world remains steeped in idolatry.
10. The Messiah brings about a universal recognition that the Jewish idea of Gd is Gd (
Isaiah 11:9).
But the world remains steeped in idolatry.
11. The Messiah leads the world to become vegetarian (
Isaiah 11:6-9).
12. The Messiah gathers to Israel all of the twelve tribes (
Ezekiel 36:24).
13. The Messiah rebuilds the Temple (
Isaiah 2:2;
Ezekiel 37:26-28).
14. After the Messiah comes, there will be no more famine (
Ezekiel 36:29-30).
15. After the Messiah comes, death will eventually cease (
Isaiah 25:8).
16. Eventually the dead will be resurrected (
Isaiah 26:19;
Daniel 12:2;
Ezekiel 37:12-13;
Isaiah 43:5-6).
17. The nations of the earth will help the Jews materially (
Isaiah 60:5-6; 60:10-12).
18. The Jews will be sought out for spiritual guidance (
Zechariah 8:23).
19. All weapons will be destroyed (
Ezekiel 39:9,12).
20. The Nile will run dry (
Isaiah 11:15).
21. Monthly, the trees of Israel will yield their fruit (
Ezekiel 47:12).
22. Each tribe of Israel will receive and settle their inherited land (
Ezekiel 47:13-13).
23. The nations of the earth will recognize that they have been in error, that the Jews had it right all along, and that the sins of the Gentile nations – their persecutions and the murders they committed – have been borne by the Jewish people (
Isaiah 53).
