God Wants You Well by Andrew Wommack
Healing is part of Christ’s atonement. If Jesus died to provide healing for us, then it’s not just incidental. If the Lord suffered and took stripes on His back for our physical healing, then it’s not insignificant. If Jesus thought enough of healing to purchase it for us, then we ought to think enough of it to receive. God the Father caused His Son to bear all of our sins and all of our sicknesses on the cross. Jesus took our diseases just as much as He took our sins. Therefore, it honors Him to promote healing.
