There is, however, another question I think we should also ask: “Do we need
to prove the existence of God?” My short answer: “No, but it’s still important to be able to do so.” I take the view, following John Calvin and other Reformed scholars, that Romans 1:18-32
teaches a universal knowledge of God: a sensus divinitatis
that is part of our human nature. On this view, every human being possesses a natural knowledge of the living and true God, even though they sinfully distort and suppress that knowledge. It’s precisely this fact that serves as the basis for God’s universal judgment. People don’t need
to have the existence of God proven to them by us.
