Four words and a long, historic pattern. "What" and "hath" both lean on the four-dot H and lone T dashes; "God" centers on the three-dash O; and "wrought" is the longest word, running W, R, O, U, G, H, T to a final T. The repeated H's and T's across the phrase give it a recurring bright-then-clipped texture throughout its length.
