1 Peter 2:24

Who His own self bare our sins in His own body on the tree, that we, being dead to sins, should live unto righteousness: by Whose stripes ye were healed.

The devil would like us to think we are dead men walking. Gods’ word said were HEALED before we ever get sick.  We have the healing, and we take hold of it by faith.  Focus on the word of God and recite the scriptures that say we are healed.  Don’t give up and don’t back down.
