God’s Prophets have always been “the intermediary” through Whom we receive everything from God

…the Apostles and Messengers of God have ever been the channels of His abounding grace, and whatsoever man hath received from God hath been through the intermediary of those Embodiments of holiness and Essences of detachment, those Repositories of His knowledge and Exponents of His Cause. (Baha’u’llah,‘The Tabernacle of Unity)
