“‘Wake, you who sleep, and rise from darkness and Christ will give you light‘ (Ephesians 5:14). Every day, Christ enlightens us by His teaching and His Spirit; and although we do not see Him with our eyes we know by experience that He is our sun.”
–John Calvin, Calvin: Commentaries (Library of Christian Classics, Vol. XXIII), Ed. Joseph Haroutunian (Philadelphia: Westminster Press, 1958), 144.
