Is faith an absolute necessity in order to beleve that God exists?

Consider this quote: ¨A casual stroll through the lunatic asylum shows that faith does not prove anything.¨

The pevious quote is the work of Nietzsche, and, as usual, he makes it known what he wants us to know. I dont know if this quote is even that necessary -or even hold any form of truth.  I rarely walk the ground of epistemilogical concepts, but I will make an exception for this one subject. Let us suppose that I beleve or hold some type of idea that is undersupported and completly speculative about X. I assume that X holds properties of which i have no knowledge of. And when asked, ¨why do you feel that X exists and holds P (properties), ¨ I merely respond, ¨I have faith that it does.¨ If thats all faith was, then I agree with Nietzsche. However, having faith and hoping for X  are two diffrent things. Just as the statments_: I feel that X is the case, and I have reason to beleve that X is the… If I have faith about something, there must be a reson for it, but if i have a reason for it then I dont have faith — or at least i dont have faith simpliceter. Now, as are reasons -reguardless if they are self-imposed, or discovered- are established, faith is now impossible for it has been eliminated. So any reason for you beleving that God exists or that X is the case cannot be claimed by faith.
