But why then did Christ come? Did He not know that they would not believe in Him? Yes: the Prophets had prohibited this very unbelief, and He came that it might be made manifest, to their confusion and condemnation; That the saying of Esaias the prophet might be fulfilled, which He spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
