Unless we could do this, we should compound them together at a venture, and form a revelation like Nebuchadnezzar's idol, "partly iron and partly clay," alias partly divine and partly human. The Apostle Paul informs us, that sometimes he "spake, and not the Lord," and at other times speaks doubtfully about the matter, saying, "and I think also that I have the spirit of God," and if he was at a loss about his inspiration, well may we be distrustful of it. From the foregoing speculations on the subject of supernatural inspiration, it appears, that there are insuperable difficulties in a mere mental discourse with the divine spirit; it is what we are unacquainted with, and the law of our nature forbids it. Our method of conversation is vocal, or by writing, or by some sort of external symbols which are the mediate ground of it, and we are liable to errors and mistakes in this natural and external way of correspondence; but when we have the vanity to rely on dreams and visions to inform ourselves of things, or attempt to commune with invisible finite beings, or with the holy spirit, our deceptions, blunders and confusions are increased to fanaticism itself; as the diverse supposed influence of the spirit, on the respective sectaries, even among Christians, may witness, as it manifestly, in their empty conceit of it, conforms to every of their traditions. Which evinces, that the whole bustle of it is mere enthusiasm, for was it dictated by the spirit of truth and uniformity itself, it would influence all alike, however zealots persuade themselves and one another that they have supernatural communion with the Holy Ghost, from whence they tell us they derive their notions of religion, and in their frenzy are proof against reason and argument, which if we tender them, they tell us, that it is carnal and depraved reasoning, but that their teachings are immediately from God, and then proceed to vent upon us all the curses and punishments, which are written in the book of the law. There has in the different parts and ages of the world, been a multiplicity of immediate and wonderful discoveries, said to have been made to godly men of old by the special illumination or supernatural inspiration of God, every of which have, in doctrine, precept and instruction, been essentially different from each other, which are consequently as repugnant to truth, as the diversity of the influence of the spirit on the multiplicity of sectaries has been represented to be.
