If one wants to hear God speak to them they need to have faith that he does in fact exist. To strengthen one's faith, faith comes by hearing and that is hearing the word of God which comes from the same book that you do not want to rely on.
So if that is the case, how do you expect to hear from him?
Many times when people hit rock bottom and they cry out to him with faith, he does answer.
People that can actually hear God talking to them always scare me.
