We must therefore admit in God’s individual works—but especially in them as a whole—that God’s powers are actually represented as in a painting. Thereby the whole of mankind is invited and attracted to recognition of him, and from this to true and complete happiness. Now those powers appear most clearly in his works. Yet we comprehend their chief purpose, their value, and the reason why we should ponder them, only when we descend into ourselves and contemplate by what means the Lord shows in us his life, wisdom, and power; and exercises in our behalf his righteousness, goodness, and mercy. For even though David justly complains that unbelievers are foolish because they do not ponder the deep designs of God in the governance of mankind [Ps. 92:5–6], yet what he says elsewhere is very true: that God’s wonderful wisdom here abounds more than the hairs of our head [cf. Ps. 40:12].
