The bend of man's knee does not indicate that it is natural for him to stand or squat and unnatural for him to sit down. It indicates that it is natural for him to build a chair. A chair allows his God-given clothes to remain clean, gives rest to his tired feet, and raises him above the chairless beasts.
Man's industry is his creational gift and birthright. He is and must be the building creature, for the yield of his work requires an altar on which it may be offered to God. Paradise is a Garden but it is also the holy City, many houses of living stones. A city with no gardens is dead, but a garden is itself a city of vegetation; an untended garden is a wilderness. The new Jerusalem, that perfect bride, descends from heaven adorned, for adornment is a woman's skill and honor regardless of the perfection of beauty it ornaments. Let the one who has toiled finally rule unbesmirched and un-footsore from thrones of his own ingenuity, harvest, and crafting. No other creature can.
