My opinion
In the name of God
I,m a 19 year Muslim and believe like this(maybe thought like this)!:
1-All Muslims should believe in Bible or any othe holy book.
2-most of the Bible isn't corrupted and can be useful to show our ways.
3-some parts of Bible surely have been corrupted,our job is to think and find those parts and don't use them in our lives because it whould lead us to a destiny that its end is not known!
