When we inject the proviso ‘if it be thy will,’ it is always an acknowledgement that we are not praying the prayer of faith, but that we have a doubt in our own heart… When you pray for the sick and insert the proviso ‘if it be thy will,’ you are placing all responsibility of that healing on God and assuming absolutely none yourself.

Why are so many true saints of God not healed? Many saints are not healed because of false teaching… These saints cannot pray the prayer of faith to be healed, because they believe it is God’s will that they should be sick, but they can, with no compunction of conscience, send for a physician and use all possible human remedies to get rid of that which God has sent upon them for their good. Human nature is indeed a funny thing… Every sick person does need a physician.
