9 Turn your attention to that word. You can have a word in your heart, as it were a design born in your mind, so that your mind brings forth the design; and the design is, so to speak, the offspring of your mind, the child of your heart. For first your heart brings forth a design to construct some fabric, to set up something great on the earth; already the design is conceived, and the work is not yet finished: you see what you will make; but another does not admire, until you have made and constructed the pile, and brought that fabric into shape and to completion; then men regard the admirable fabric, and admire the design of the architect; they are astonished at what they see, and are pleased with what they do not see: who is there who can see a design?
If, then, on account of some great building a human design receives praise, do you wish to see what a design of God is the Lord Jesus Christ, that is, the Word of God? Mark this fabric of the world. View what was made by the Word, and then you will understand what is the nature of the world. Mark these two bodies of the world, the heavens and the earth. Who will unfold in words the beauty of the heavens? Who will unfold in words the fruitfulness of the earth? Who will worthily extol the changes of the seasons?
Who will worthily extol the power of seeds? You see what things I do not mention, lest in giving a long list I should perhaps tell of less than you can call up to your own minds. From this fabric, then, judge the nature of the Word by which it was made: and not it alone; for all these things are seen, because they have to do with the bodily sense. By that Word angels also were made; by that Word archangels were made, powers, thrones, dominions, principalities; by that Word were made all things. Hence, judge what a Word this is.
