What about the people [when the Spirit is moving a preacher]? They sense it at once; they can tell the difference immediately. They are gripped, they become serious, they are convicted, they are moved, they are humbled. Some are convicted of sin, others are lifted up to the heavens, anything may happen to any one of them. They know at once that something quite unusual and exceptional is happening. As a result they begin to delight in the things of God and they want more and more teaching.
