Calvin on the sensus divinitatis (or sense of the divine):
There is within the human mind, and indeed by natural instinct, an awareness of divinity. This we take to beyond controversy. To prevent anyone from taking refuge in the pretense of ignorance, God himself has implanted in all men a certain understanding of his divine majesty . . . Therefore, since from the beginning of the world there has been no region, no city, in short, no household, that could do without religion, there lies in this a tacit confession of a sense of deity inscribed in the hearts of all.
Someone may object that non-religious households exist. But it would be easy enough to demonstrate that these apparently non-religious households are ordered around some object whether it is sports, entertainment, power, or materialism. As Bob Dylan said, “You’ve got to serve somebody.”
