Christians: Wouldn't it be considered blasphemy to say that God exists?

no. knowing he exsts doesnt mean we have solid proof of him existing . we KNOW he exists because of the faith we have. i have faith in god, in knowing that he loves me more than anyone does, more than anyone ever can and in knowing that he is watching over me and looking after me. he has never spoken directly to me, but the bible is his way of communicating with his people.
