Jesus had no traits of a King who would save Jews from their enemies as the OT prophets anticipated. Why are these prophecies fabricated?
I assume that this criticism is coming from a Muslim source. You begin with an erroneous premise, which makes your question a nonsense question. I will share with you below a number of royal prophecies fulfilled by Jesus as king. However, to be honest, you need to back up your original premise that Jesus did not fulfill the royal expectation of the Messiah. Simply saying something does not make it true. Please supply for me passages which are surely messianic which Jesus did not fulfill. I believe that there are none. Without evidence to back up your premise, your question is not even a valid question, deserving of answer.
In the meantime, here are a few royal messianic prophecies that Jesus certainly fulfilled.
Psalm 110:1-7 Jesus is a priest of the Order of Melchizedek, as is proved by Hebrews 7. If you read Revelation you will see that Jesus, riding on a white horse, does indeed crush all the earthly kings
Zechariah 9:9 See, your king comes to you, righteous and victorious, lowly and riding on a donkey. Obviously, Jesus fulfilled this prophecy, as is celebrated every year on Palm Sunday.
2 Sam 7:14 in which David is told that he will have a direct descendant to rule on his throne forever. Jesus was a direct descendant of David, even being born in Bethlehem. Jesus is reigning, even now, in heaven as head of the kingdom of God.
Isaiah 11:1 Similarly, the Messiah is the root of the stump of Jesse–of David. Jesus, as direct descendant, and as the one who fulfilled Isaiah 53, Micah 5:2, Isaiah 9:1-6 and others is that root of Jesse.
That Jesus saved the Jews from their REAL enemy, which is Satan, is clear. Jesus offered salvation from sin to anyone. He is the victorious king who wins victory over sin and Satan. Like Paul said, “first for the Jew, then for the Gentile.” Jesus saved the Jews from their real enemy, which was Satan all along. Jesus set up a kingdom that will never be destroyed. (Daniel 2, Daniel 7)
Again, this answer is moot. Unless you can supply a single messianic prophecy which you say that Jesus did not fulfill this prophecy, then your point is not valid and, to be honest, no answer is required. Please supply the prophecies that form the premise of your statement.
Besides, you ask why the prophecies are fabricated. What do you even mean by that? In what sense were these prophecies (that you have not even listed) fabricated? Are you saying that they were not in the original Old Testament in the first place? Surely not. Or are you saying that Jesus did not fulfill them, which makes no sense if the prophecies themselves were fabricated (ie not part of the original). I am confused. Please explain.
