"Who forgiveth all thine iniquities; who healeth all thy diseases" (Ps. 103:3).
Disease came upon the children of Israel when they disobeyed the law. Forgiveness for their disobedience meant the healing of their diseases.
It was when the children of Israel took themselves out from under the protection of their covenant by wrongdoing that their distresses came (Ps. 107:11,17-18).
But when they cried unto the Lord, "... He saveth them out of their distresses. He sent his word, and healed them, and delivered them from their destructions" (Ps. 107:19-20).
We have protection under our better covenant, but it is possible to take ourselves out from under the protection of our covenant.
Since I have known the truth of God's Word concerning divine health and healing, the only time some physical disorder touched me was when I got out from under God's protection.
Now, I don't mean I stole something or told a lie; I just wasn't obeying God like I should have been. (Usually, I wasn't ministering the way God said to minister.)
Therefore, I got out from under the protection of the covenant and opened myself up to the enemy's attacks. So I had to repent and get back in line. The moment I did, I was healed physically.
Confession: God forgives iniquities. God heals diseases. He sent His Word and healed me. He delivered me from destruction.
