It has been said severally that the bible was written by over 40 people who were all inspired by God. It is also written that it took over 300years for the bible to be completely written. As we all know, the bible recorded so many past events (like how the world came into existence, miracles of Jesus, destruction of the world, etc). I honestly do not believe that everything in the bible really happened. Some never happened while many were not written exactly the way they happened. Some of the things can't just possibly happen. Do you feel the same way or otherwise?

Which part of the bible that find hard 2 blive?

If you don't believe everything in the bible, then you don't believe the bible. A passage you consider false goes a long way in question of the veracity of the rest. A lil contradiction of facts impairs the whole book.

I believe so much in the power of the supernatural, so why should any miracle or event in the Bible be that hard to believe?.

I believe all the events did happen.
