Faith takes hold of what the grace of God has already provided. God does not need to do anything else. Faith enables what God has already done to flow from spiritual to physical. Receiving from God may be thought of as like a board game when after one person moves he has nothing to do until the other moves. Each person moves in his turn. When God has provided healing or any blessing & sent us His Word it is our move. Our move is to expect what He promises when we pray causing us to act on our faith before we see the healing. When Noah was warned of God of things not seen as yet Heb.11:7 his move was to believe that a flood was coming & to act on his faith by building a ship on dry land. When God says to any sick James 5:14-15 The prayer of faith shall save the sick & the Lord shall raise him up we like Noah are informed by God of things not seen as yet and our move is the same as Noah’s, to believe & act accordingly. Fallen nature is governed by what it sees and by its senses but faith is governed by the pure Word of God and is nothing less than expecting God to do what He promises. Sick people when prayed for naturally hope they will be better but the natural human emotion of hope is only passive quite different from Bible faith which is active & creative. To just hope for something indicates uncertainty. It has no basis for expectancy. But faith looks back to what Christ accomplished for us in His death as our substitute. Faith rests with confident assurance in God's word, even while it receives no encouragement at all by what the eye can see. The natural person is a creature of the senses. Feeling or seeing the symptoms of an affliction he or she tends to believe what the senses register rather than what God's word says. Faith by contrast is not influenced by what the eye sees & is indifferent to it. It does not honour the natural senses but draws its strength from the unchanging word of God. If this were not the nature of faith no such thing as faith would be necessary. Why should faith be needed for that which the eye can already see or the hand can already feel? The truth is that the healing of the body and the salvation of the soul involve a similar work of the Spirit and are governed by very nearly if not identical laws. After we have some appreciation of the awfulness of the disease of sin & express a willingness to forsake it, we still will not be saved without believing that Christ died in our place. Only when we accept the finished work of redemption can we be saved. If we will not believe until we feel saved, we may never be saved. It is only in the act of believing the finished work of redemption that conversion takes place. Faith never waits to see before it believes, because it comes by hearing Rom.10:17 about things not seen as yet Heb.11:7 & it is the evidence of things not seen v.1 All that a man of faith needs is to know that God has spoken. The Lord has said settles everything. Healing is a finished work as far as God is concerned. We have to appropriate it by faith, knowing that the work is done already. What we do is take a hold of healing the same way that we take hold of salvation. Faith takes hold of what God has already provided by grace. Faith means we are confident of what we hope for convinced of what we do not see Heb.11:1. We are convinced because God who cannot lie has spoken. Faith is therefore most rational.  It is not believing without evidence but believing because of the very highest possible evidence God’s Word. It is like a title deed. We have to move in & possess what we own. His compassionate heart yearns to heal us more than we have the capacity to desire it. We keep Him waiting until we have the faith that comes by hearing & act on it Rom 10.17
