Please pray

Well, I would greatly appreciate it if you could pray for my brother. It is horrible to see how sickness can take away someone's spirit in all that he does. For several years now, my brother has been struggling with severe sickness in his stomach and actually all of his body. School has always been a good disctraction, but currently he is between schools and his sickness is really starting to take over his life. Besides it already controlling what he eats, drinks, and what he can all do. It is effecting him everywhere right now. He is just tired, doctors don't really know what it is, and there is not really a cure, according to those that think they know what it is. Please pray, for strength, that he might feel renewed in energy and courage. Also pray for healing, some sort of healing in whatever form that comes. In Christ's name, Amen
