We can be healed through the authority of the Melchizedek Priesthood. Jesus gave His Apostles power "to heal all manner of sickness and all manner of disease," and they went forth "preaching the gospel, and healing every where." The Seventy were also sent forth with power and direction to heal the sick. Although the Savior could heal all whom He would heal, this is not true of those who hold His priesthood authority. Mortal exercises of that authority are limited by the will of Him whose priesthood it is. Consequently, we are told that some whom the elders bless are not healed because they are "appointed unto death." Similarly, when the Apostle Paul sought to be healed from the "thorn in the flesh" that buffeted him, the Lord declined to heal him. Paul later wrote that the Lord explained, "My grace is sufficient for thee: for my strength is made perfect in weakness." Paul obediently responded that he "would rather glory in my infirmities, that the power of Christ may rest upon me ... for when I am weak, then am I strong."
