On God’s Stationary Earth and Revolving Heavens
A simple survey of the world should of itself suffice to attest a Divine Providence. The heavens revolve daily, and, immense as is their fabric, and inconceivable the rapidity of their revolutions, we experience no concussion — no disturbance in the harmony of their motion. The sun, though varying its course every diurnal revolution, returns annually to the same point. The planets, in all their wanderings, maintain their respective positions. How could the earth hang suspended in the air were it not upheld by God’s hand? By what means could it maintain itself unmoved, while the heavens above are in constant rapid motion, did not its Divine Maker fix and establish it? Accordingly the particle אף, aph, denoting emphasis, is introduced — Yea, he hath established it.
(John Calvin – Commentary on the Psalms: Volume 4 – Psalm 93:1)
