I come across some who would be giants in the power of God but they have no shout of faith. I find everywhere people who go down [fail] even when they are praying simply because they are just breathing sentences without uttering speech, and you cannot get victory that way. You must learn to take the victory and shout in the face of the devil, "It is done!" There is no man who can doubt if he learns to shout.
