One of the basic principles of responding correctly to God’s grace is that if Jesus has already done something, there is no need for us to try to do it ourselves. This applies to many areas of our lives, including our healing. As Christians, we receive good health and take possession of it by faith. We have been healed on every level; when we believe this, we will know how to respond to the doctor’s report when it contradicts God’s Word. The final authority on our healing is not a physician’s diagnosis, but what God says. When things look grim, we need to know that it is God’s will for us to be healthy. Agreeing with this positions us to receive what He wants us to have.
