Look at the "dress" of birds and see how easily they can ruffle or set their feathers and yet use them continually. Giving things bodies and dressing them in forms in a wise manner without waste and futility bears witness to the number of those things to an All‑Wise Maker's necessary Existence and points to an Absolutely Powerful and Knowing One.
