Charistian has been claiming that bible has never been changed and claiming that even you holy book Quran ssays bible is guidance and noor, so why you are not claiming bible as word of GOD,and muslim has no evidance about change

I think you do not know that there are many different versions of the Holy Bible. It is an established fact that the Holy Bible is definitely not in its original shape.

As you already know that Hazrat Essa alaihissalaam or the Jesus Christ is one of our beloved prophets. He was sent for the Bani Israel. It is said that the language of the people at that time and place was Hebrew. Hence the text of the Holy Bible should have been in Hebrew, but the first authentic version as it is claimed was written in Greek.

The claims of the Christians that the Holy Bible has never changed is incorrect. If you need more details, I would suggest you listen to the lectures of Dr. Zakir Naik on Christianity and Islam

Here`s a Verse to them about Nuur: 5:15
And here: 9:32
And here: 39:22
There does not exist a Verse in The Book of Allaah that The Bible is hudaa wa nuur. But I recall reading that about Toorah, and Allaah knows best -I couldn`t find the Ayah. That`s probably what they are referring to. The Toorah is hudaa and nuur, the Zubuur is hudaa wa nuur, and the Injeel is hudaa wa nuur. None of these equals with the book called `The Bible`, as is a historical fact known to the scholars of christianity themselves. What in fact they claim in order to go around this reality, is that `the holy ghost` has guided men other than the Prophets of Allaah -may Allaah grant them Peace- so that The Bible somehow became Revelation. Anyone can make such a claim. They have no proof for it.

Besides, God is One, not three.
