Faith is the action that corresponds with what we see with our spiritual eyes. In other words we can not see a healing take place with our natural eyes until after it happens, but with our spiritual eyes we can see the finished healing and the results associated with that. Someone with a bad back for instance in the natural may not be able to touch their toes but looking in the spirit at that person whole they can. This does not mean that because we know what the results should be we try to produce the results by our own efforts but when we see it in the spirit we act on it. What we see in the spirit can sometimes be the means of action to take so that which is seen in the spirit becomes manifested in the natural.
In most cases what we see in the spirit is a result of a truth or a conviction in our heart that declares what one is experiencing is contrary to the finished works of Jesus, which is not the will of God, and needs to be corrected. Jesus moved in compassion and this compassion that swelled up in him was a result of knowing what the truth looks like and then moving to correct the wrongs. God desires a quality of life for all of humanity which enables us to experience His best daily as the normal and not the unusual part of our daily lives.
