People often fear trying to hear God in their spirit for fear of the presumption of hearing God speak. But hearing God is a relational, personal thing. It is not meant to be weighed and examined as if it has to pass for Scripture.
Your hearing will not be perfect, because you have filters, as we all do. Filters composed of fears, passions, prejudices and doctrines. Yet listen and hear we must, if we are to experience the fullness of life Jesus promises.
