On Counter Promises
4 But if these views should not appear to fill the minds of those who hope for such results with a becoming desire, let us go back a little, and, irrespective of the natural and innate longing of the mind for the thing itself, let us make inquiry so that we may be able at last to describe, as it were, the very forms of the bread of life, and the quality of that wine, and the peculiar nature of the principalities, all in conformity with the spiritual view of things. Now, as in those arts which are usually performed by means of manual labour, the reason why a thing is done, or why it is of a special quality, or for a special purpose, is an object of investigation to the mind, while the actual work itself is unfolded to view by the agency of the hands; so, in those works of God which were created by Him, it is to be observed that the reason and understanding of those things which we see done by Him remains undisclosed. And as, when our eye beholds the products of an artist's labour, the mind, immediately on perceiving anything of unusual artistic excellence, burns to know of what nature it is, or how it was formed, or to what purposes it was fashioned; so, in a much greater degree, and in one that is beyond all comparison, does the mind burn with an inexpressible desire to know the reason of those things which we see done by God. This desire, this longing, we believe to be unquestionably implanted within us by God; and as the eye naturally seeks the light and vision, and our body naturally desires food and drink, so our mind is possessed with a becoming and natural desire to become acquainted with the truth of God and the causes of things. Now we have received this desire from God, not in order that it should never be gratified or be capable of gratification; otherwise the love of truth would appear to have been implanted by God into our minds to no purpose, if it were never to have an opportunity of satisfaction. Whence also, even in this life, those who devote themselves with great labour to the pursuits of piety and religion, although obtaining only some small fragments from the numerous and immense treasures of divine knowledge, yet, by the very circumstance that their mind and soul is engaged in these pursuits, and that in the eagerness of their desire they outstrip themselves, do they derive much advantage; and, because their minds are directed to the study and love of the investigation of truth, are they made fitter for receiving the instruction that is to come; as if, when one would paint an image, he were first with a light pencil to trace out the outlines of the coming picture, and prepare marks for the reception of the features that are to be afterwards added, this preliminary sketch in outline is found to prepare the way for the laying on of the true colours of the painting; so, in a measure, an outline and sketch may be traced on the tablets of our heart by the pencil of our Lord Jesus Christ. And therefore perhaps is it said, “Unto every one that has shall be given, and be added.” By which it is established, that to those who possess in this life a kind of outline of truth and knowledge, shall be added the beauty of a perfect image in the future.
5. Some such desire, I apprehend, was indicated by him who said, “I am in a strait between two, having a desire to depart, and to be with Christ, which is far better;” knowing that when he should have returned to Christ he would then know more clearly the reasons of all things which are done on earth, either respecting man, or the soul of man, or the mind; or regarding any other subject, such as, for instance, what is the Spirit that operates, what also is the vital spirit, or what is the grace of the Holy Spirit that is given to believers. Then also will he understand what Israel appears to be, or what is meant by the diversity of nations; what the twelve tribes of Israel mean, and what the individual people of each tribe. Then, too, will he understand the reason of the priests and Levites, and of the different priestly orders, the type of which was in Moses, and also what is the true meaning of the jubilees, and of the weeks of years with God. He will see also the reasons for the festival days, and holy days, and for all the sacrifices and purifications. He will perceive also the reason of the purgation from leprosy, and what the different kinds of leprosy are, and the reason of the purgation of those who lose their seed. He will come to know, moreover, what are the good influences, and their greatness, and their qualities; and those too which are of a contrary kind, and what the affection of the former, and what the strife-causing emulation of the latter is towards men. He will behold also the nature of the soul, and the diversity of animals (whether of those which live in the water, or of birds, or of wild beasts), and why each of the genera is subdivided into so many species; and what intention of the Creator, or what purpose of His wisdom, is concealed in each individual thing. He will become acquainted, too, with the reason why certain properties are found associated with certain roots or herbs, and why, on the other hand, evil effects are averted by other herbs and roots. He will know, moreover, the nature of the apostate angels, and the reason why they have power to flatter in some things those who do not despise them with the whole power of faith, and why they exist for the purpose of deceiving and leading men astray. He will learn, too, the judgment of Divine Providence on each individual thing; and that, of those events which happen to men, none occur by accident or chance, but in accordance with a plan so carefully considered, and so stupendous, that it does not overlook even the number of the hairs of the heads, not merely of the saints, but perhaps of all human beings, and the plan of which providential government extends even to caring for the sale of two sparrows for a denarius, whether sparrows there be understood figuratively or literally. Now indeed this providential government is still a subject of investigation, but then it will be fully manifested. From all which we are to suppose, that meanwhile not a little time may pass by until the reason of those things only which are upon the earth be pointed out to the worthy and deserving after their departure from life, that by the knowledge of all these things, and by the grace of full knowledge, they may enjoy an unspeakable joy. Then, if that atmosphere which is between heaven and earth is not devoid of inhabitants, and those of a rational kind, as the apostle says, “Wherein in times past you walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the children of disobedience.” And again he says, “We shall be caught up in the clouds to meet Christ in the air, and so shall we ever be with the Lord.”
