“All nature, including the nature of man, is a wondrous instrument of many strings, delicately tuned to work God’s will and upon which he plays with a master hand. But all such figures of speech go only a little way; there is a point at which they break down. The relationship of God to the course of nature is vastly more intimate than the relationship of a musician to the instrument upon which he plays. The musician is outside of his instrument as the engineer is outside of the machine that he controls and guides. But God pervades the course of nature. No recess of it is apart from him; he pervades it through and through. Infinitely separate, yet everywhere near — such is the great mystery of the immanence and transcendence of God.” — J. Gresham Machen, Things Unseen: A Systematic Introduction to the Christian Faith and Reformed Theology (2020), p. 215
