4. Therefore in order to remove all doubt as to such being the character of the Word, the Lord has revealed to me the Word's internal sense. In its essence this sense is spiritual, and in relation to the external sense, which is natural, is as soul is to body. This sense is the spirit which gives life to the letter; it can therefore bear witness to the divinity and holiness of the Word, and convince even the natural man, if he is willing to be convinced.
