Yet Christian disbelief does not mean the practice of a principled doubt about everything, in a false fear that naive affirmations get mugged by jaded realities. Such an all-encompassing dubiety soon slides into cynicism—into a pessimism altogether as sentimental and self-serving as the easy optimism it rejects. Mark Twain thus described a pessimist as an optimist on all-fours. Christian disbelief is, instead, a positive testing of what is true and false by a single criterion: “By this you know the Spirit of God: every spirit which confesses that Jesus Christ has come in the flesh is of God, and every spirit which does not confess Jesus is not of God” (I John 4:2-3).
Taken from this very thought-provoking essay. Do read it if you have time (or even if, like me, you don’t). Spent the whole of yesterday afternoon doing absolutely nothing productive (the header above is evidence heh) and .. wow. I’m so calm now I think maybe I should do nothing more often 😀
