Total healing can only come from God, even doctors say "Men like them can only cure diseases but Healing comes from God", they themselves acknowledge the power and the role of Christ in our health, this is Divine Health.
Behind every word in scripture is the Spirit of God. The breath of God is what quickens, and healing virtue is transmitted whenever the Word IS being preached. God sent out His Word (His Son) and our diseases were healed.
