From these things the difference will scarcely fail to be apparent between true and imaginary wisdom, or between that wisdom which is the Lord's gift, and that which is procured by man's own endeavor: as also that the one is insinuated through the former way, and is thus full, or fully formed; while the other [is received] through the latter way, and is, consequently, constrained, closed, unformed; in a word, [the difference may be perceived] between the faith appropriate to either kind of wisdom, and that one who is not in saving faith can by no means, even with all the force of his intellect, perceive how the case is with saving faith in these and the like things, consequently, what the quality of heaven is, when yet these things in heaven are so known, manifest, and clear, that they [who dwell there] now say that they not a little wonder how the human race should be so insensate as to be unable to understand the true state of the fact, when it is as now described. Such is faith in the heavens, such the doctrine of faith, such the doctrine of those who are in faith.
