"Now it is only thus helpless and useless in religion; it is neither seeing, nor hearing, tasting, nor feeling of spiritual things; therefore in the things of religion, and in the things of this world, it has one and the same insignificance. It is the sensibility of the soul that must receive what this world can communicate to it; it is the sensibility of the soul that must receive what God can communicate: reason may follow after in either case, and view through its own glass what is done, but it can no do no more. Reason may be here of the same service to us, as when we want any of the enjoyments of this life; it may direct us how and where they are to be had; it may take away a cover from our eyes, or open our window shutters when we want the light; but it can do no more towards seeing, than to make way for the light to act upon our eyes. This is all its office and ability in the things of religion; it may remove that which hinders the sensibility of the soul, or prevents the divine light's acting upon it, but the activity of the mind upon its own ideas or images, which the senses have caused it to form from that which has been stirred up in them, but has nothing of the nature of that which it speculates upon by ideas; it does not become dark, when it reasons upon the cause or nature of darkness, nor becomes light, when it reasons about it; neither is it religion, nor gets anything of the nature of religion, when it is wholly taken up in descriptions and definitions of religious doctrines and virtues.
