We must be able to show people that the gospel is what it claims to be. When a world-class athlete stands on the track, we do not need to argue to prove that he is a champion. Just fire the starting pistol! That is what I do—the gospel of Christ is alive, so I go into a stadium and let the gospel do its own thing, and everybody can see it is alive. That is what the Holy Spirit does. I have seen countless mighty wonders wrought and unclean spirits cast out by the finger of God.
