This is David. I was questining the author's original post about those that did not 'keep the law' having abominable prayers. I would like to suggest digging into the definition of the word translated as saved in the gospel. Also, Psalm 103:3-5 seems to indicate a that healing from disease as part of the covenant established between God and the seeker. This is a difficult topic, because obviously people that are wonderfull Christians get sick and die. I believe the idea of sickness occurring for the sake of the glory of God may be a missunderstanding of the point being made about the man blind from birth that Jesus healed. When the nuance and inflection of the Greek is looked at, I have read that the healing was for the furthurence of the Kingdom, not the actual ailment. I don't read Greek, so I don't know. I do know that the advasary came only to steal, kill, and destroy and Jesus came, in part, to destroy the work of the devil and that we may have fullness of life which would include health. I think I read earlier where you referenced healthy habits. I feel this is very important, because the LordGod stated that at times we perish because of a lack of knowledge, be it of our authority as children of God or biology. I have been healed through simple belief in the power of the covenant, a word of prophetic knowledge followed by an act of faith, and taking authority over my body expressed by actually talking to it, as well as commanding negative spirits that I discerned were oppressing me. A fantastic book on healing is entitled "Healing" and was written by Francis NcNutt.
Keep on the path, my brother, and keep asking good questions.
