Re: ...Studying Bible...
My knowledge says that The old Testament (Torah) and Gospel (Injeel) are not in their pure form anymore as testified by Quran in many places. To read them is like to seek wrong information. However, I follow the opinion of Dr. Zakir Naik who reads these books, even Geeta, for comparitive study and to prove Quran is different and correct in context as compare to the existing text of those once divine books.
Believing in them is part of our iman and Quran does say that there is light in Torah and Injeel (Gospel) but light it refers to was actually in the original text which is not available anymore.
