I do not believe that ordinary humans ever had the ability to hear God; not hundreds, thousands, or ten thousand years ago. I believe that only Messengers of God (Manifestations of God) have the ability to hear God. Below is the basis for that belief.
A Messenger of God is not an ordinary man. Messengers of God, what Baha’is normally refer to as Manifestations of God, possess two stations: one is the physical station pertaining to the world of matter, and the other is the spiritual station, born of the substance of God. In other words, one station is that of a human being, and one, of the Divine Reality. It is because they possess both a human and a divine station that they can act as *mediators* between God and man.
Every Manifestation of God is a mirror of God, reflecting God’s Self, God’s Beauty, God’s Might and Glory. All other human beings are to be regarded as mirrors capable of reflecting the glory of these Manifestations Who are themselves the Primary Mirrors of the Divine Being,
The Manifestations of God are another order of creation above an ordinary man. Their souls had pre-existence in the spiritual world before their bodies were born in this world, whereas the souls of all humans come into being at the moment of conception. The spiritual world is where They get their special powers from God. They possess a universal divine mind that is different than ours and that is why God only speaks to them directly and through Them God communicates to humanity.
