He sent forth his word and healed them; he rescued them from the grave.
(Psalm 107:20 NIV84)

When our diet is poor lacking quality nutrients then our immune system suffers and we can become ill with a virus prompting us to visit a clinic for medical care. When our spiritual diet is poor lacking the Word of God our good judgment suffers and our soul becomes ill from sin. We need to visit a church to hear that healing Word which sets us free.
