You and other Prosperity Gospel preachers advance a vision of God that is transactional: if you do this, then God will do that. He has to, in fact. Because a verse here or there in the Bible says so, however little it reflects God's actual redemptive work in the world.
And I'm here to tell you, Sir, in the same language I use with anyone who imagines we can be in a transactional relationship with God, that this isn't what Christian faith is. Praying the right prayer often enough to get what you want, believing really hard in Jesus to get what you want are not true to the Christian story, or to logic. To imagine that you, or your followers, or the person out in the bookstore or TV land who is exposed to your message somehow influences the God of the Universe, the Creator of All That Is, by his or her personal actions is not belief in God.
It's belief in magic. Put your hands together, say a few faithful words, and the Universe will give you what you ask.
