For Calvin, the creation reflects its Creator at every point. Image after images flashed in front of our eyes, as Calvin attempts to convey the multiplicity of ways in which the creation witnesses to its Creator: it is like a visible garment, which the invisible God dons in order to make himself known; it is like a book in which the name on the Creator is written as its author; it is like a theater, in which the glory of God is publicly displayed; it is like a mirror, in which the works and wisdom of God are reflected.

Martin Luther arrived at his earthshaking conclusions imbued with biblical exposition. As a professor, he taught the book of Psalms verse by verse from 1513 to 1515, Romans from 1515 to 1516, Galatians from 1516 until 1517, the book of Hebrews from 1517 to 1518 and then the Psalms again from 1519 until 1521.
