Imagery and idea structure are present among us as powerful governing life forces. These images and ideas are either (1) reality (example: we are beloved of God) which moves us toward Him or (2) lies/falsehood (example: God is untrustworthy and we therefore must take life into our own hands) which moves us away from God.
Satan uses imagery and Idea structure to undermine the purposes of God:  Satan, “Did God say…..??”
Mental health fundamentally serves to loosen the grip of fallen imagery and its underlying false idea structure.
