Baked over or done?

Just read this in a book by Emerson Eggerichs:

I heard a godly man with cerebral palsy speak. he had a delightful wit: "God is preparing me for heaven...I am in His oven, so to speak. I am being baked for an eternal purpose. I am not finished yet. When I die and stand before Him, He is going to say, 'Well done.'"
