Believe that you are well and trust God. God has given us the power and the anointing to be heal and to rest in his healing. I just recently read a great word regarding healing. It was article from Andrew Wommack Ministries, entitled "God Wants you Well". It discusses the different between believing God can heal and believing God wants to heal every person. The just of the article is when you pray it becomes a prayer of faith. You must Known that you Know that Jesus healed us all. When you pray believe you are healed not when you see it manifest.
Mark 11: 24
"What things soever ye desire, when ye pray , believe that ye receive them and ye shall have them"
Keep the Faith and be healed. To God Be the Glory!
