Only by writing Holy with Bible does not make it the word of God. Part of it, yes, may be the word of God but the whole series of Bibles, OT and NT are not the word of God at all.
You see there is no Gospel of Jesus (peace be upon him) or Gospel of Allah on the face of this earth. These Gospels were writen by several others like Mark, John, Mathew, Luke. In contrast, the word of Allah and the word of Jesus (pbuh) was only ONE. Later on, these Gospels were changed and interpolated from time to time by several people despite that Allah prohibited them to do so in Revelations.
Secondly, the writting of OT was started after 150 years approx. of Jesus (pbuh), so automatically this large time gap between the spoken words and the start of written words gave rise to extreme doubts and uncertainties. And the first written Gospel was not in the Hebrew language of Jesus (pbuh).
Thirdly, there are grave defects in these Gospels ranging from Pornography, Mathematical Mistakes, Scientific Errors and Plagiarism to Unknown authors. How can you attribute these kind of things towards God ???
SO PLEASE DO NOT ATTRIBUTE THESE THINGS TOWARDS ALLAH
Qur'an, Ch 2-The Cow, V 79: "Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!- Woe to them for what their hands do write, and for the gain they make thereby."
Revelation 22:18-19 ". . . If any man shall add to these things (or delete) God shall add unto him the plagues written in this Book."
But who cares! They do not really believe!
