Being and Becoming by Bavinck

"Natural mechanism cannot be the final cause and explanation of everything, since it asks for an explanation itself: natural mechanism is not lord of the world, but servant of the spirit. The forms in which it operates--time and space, measure and numeral, order and law--are basic categories of the spirit. Just as a machine serves man, natural mechanism must be subservient to the governing and leading of a divine mind that rules over all.

This does provide room for development in the true sense of the word. If the whole world is nothing but one big machine, then development is excluded. Whoever says development says plan and law, direction and goal. Development stands between beginning and end; it leads from beginning to end.

Development is not a mechanical concept, but an organic, teleological concept. For that reason it can only receive its full due on the basis of creation, which grants the world its being and which at bottom and in principle is what it has to become. Aristotle already understood that becoming exists for the sake of being, not the reverse. There is becoming only if and because there is being."
