Unmistakable Marks of Glory

Calvin:

The final goal of the blessed life, moreover, rests in the knowledge of God. Lest anyone, then, be excluded from access to happiness, he not only sowed in men's minds that seed of religion of which we have spoken but revealed himself and daily discloses himself in the whole workmanship of the universe. As a consequence, men cannot open their eyes without being compelled to see him. Indeed, his essence is incomprehensible; hence, his divineness far escapes all human perception. But upon his individual works he has engraved unmistakable marks of his glory, so clear and so prominent that even unlettered and stupid folk cannot plead the excuse of ignorance.

—John Calvin, The Institutes of the Christian Religion 1.5.1
