We are instructed to pray for God's Kingdom to come and His will to be done - on earth AS IT IS in heaven. Establishing "pain-free" zones in people's bodies is part of this mandate. Revelation 21:4 tells us that in heaven there is NO PAIN, and therefore we need to bring that 'pain-free' realm and release it into the lives of the people we minister to - physical pain, emotional pain. All types of pain are absent in heaven and therefore we can and should seek to eliminate them here.
