Both, the bible an the philosophy of Nietzsche, seems to be very contrary. I still read both. Both have shaped my philosophical understanding, but I have also included many other philosophies. (Carl Jung, Rudolph Steiner, ... )

Nietzsche was sure, that his book will become the new bible in future. And indead, he was his time far ahead. His philosophy is still our time ahead. 

It is remarquable, to notice that the ideas from Nietzsche has much in common with the Bible. And both are leading to the same path, but with different approaches. At this point, it has to be noticed, that the impact of the church destroyed the initially idea of Christianity. 

According to Nietzsche, the highest we can reach is to become a child again after a life of suffering. The suffering is necessary to understand the social structrure and to give up old values and virtues. We need to bear burden until we decide to shake them off and become free. These steps are fullfilled "easily", but finding yourself back as child is the hardest part, what only few one can reach. At this point, we are becoming in transdence with ourself. We are basically our own god.

The Bible also speaks of a path of suffering that is necessary to be formed. (for example: the dispersion and reunification of the Israelites.) The path to find god and unify with him, is often missunderstood. At the end of this journey, we are going to find out, that we were our own god ourself all the time and we chose this path to grow our soul. We will recognise how meaningsless social recognition and money has been.

I think that every philosophical person has to read Nietzsche, espacially as a theist. He will not become an atheist, but rather see god and this world though as very different lens.
