Isaiah 53 Verse 10

[Praise El Shaddai]

So you are saying the Jewish people are taking passages and making them fit into what they want to hear?

First we have to distinguish:
There are all kinds of Jews, some who don't believe in god, few who believe that Jesus was the Messiah and others who believe in the god JHWH of the "old testament" (what you call the "Hebrew bible"!?)

And about those last group of Jews (probably the majority) I think they don't want to hear these passages where it is written that the Messiah will have to suffer:

Isaiah 53:
"4 Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted.
5 But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed.
6 All we like sheep have gone astray; we have turned—every one—to his own way; and the Lord has laid on him the iniquity of us all.

It fits just so perfectly to Jesus, that it is overwhelming prophecy.
He is the promised Messiah, voluntary sacrifce to burden our sins to become redeemer for all mankind and conquerer of death, got resurrected by god and is alive. I believe that.

Do we need a Temple to be forgiven for our sins? What does the Hebrew bible say?

You are right, a temple is not needed, but after the old bond of Moses there is sacrifice needed, blood. Or not?

The Hebrew bible clearly explains what the world will be and look like.

The bible I am reading and every bible so far I have seen is written with all its 66 books completely by Jews or Israelites. Maybe I miss 1 or 2 non Israeli autors, then please correct me.
But almost everything about the one true god is passed down by Jews, even all the books, letters and scriptures between 0-100 AD about Jesus and the Apostles. It is just that Jews and many others don't want to believe them.

As far as I can see, when I look at the world and what has happened in the past 2000 years or so, none of it has happened or maybe some of it is just starting to happen.

I don't understand what you mean by that.... what should happen or not?
But it is all happening according to what Jesus said:

Mat. 24:
12 And because lawlessness will be increased, the love of many will grow cold.
13 But the one who endures to the end will be saved.
14 And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.

That time is now. All need to know that there is hope if they repent and follow Jesus the anointed king by god...
the Messiah. Sorry I can't and don't want to convince anybody, it is just the truth I need to speak of.

Grace and peace from god!
