Our Lord says, "It is expedient for you that I go away, or that comforter will not come"; that is, it is expedient for you, that I leave off teaching you in words, that sound only into your outward ears, that you may have the same words in writing, for your outward eyes to look upon; for if I do not depart from this vocal way of teaching you, the comforter will not come, that is, ye will not have the comfort of my words written on paper. But if I go away, I will send written books, which shall lead you into such a truth of words as you could not have, whilst they were only spoken from my mouth; but being written on paper, they will be my spiritual, heavenly, constant abode with you, and the most supreme illustration you can receive from me.
