I offer you a break from Advent, in the form of some light philosophy.
Alister McGrath makes a neat distinction in this piece. That we should all be epistemological agnostics, admitting that science and logic can never tell us whether God exists. But that is separate from our practical choice. In our daily lives we must choose to live either as an atheist or as a theist, despite both of those options requiring faith. Bertrand Russell was a good demonstration of this: he was humbly an agnostic, but lived practically as Britain’s foremost atheist.
“Existentially significant beliefs lie beyond proof, no matter what those beliefs might be. As philosophers of religion have emphasized throughout the history of their discipline, we have to learn to live with probable, not proven, beliefs.“
