Health is of vital importance to most people.  We do not realise the importance of something until we lose the ability to do it.    God’s word can be that healing agent you are looking for.  

“Gracious words are a honeycomb, sweet to the soul and healing to the bones.”  Proverbs 16:24

God’s word is the most gracious word you can hear and causes a merry heart.  

A merry heart does good, like medicine, But a broken spirit dries the bones.” Proverbs 17:22
