Towards the end of last year I read Hell is the Absence of God, a novella by Ted Chiang. Billed as SF but to me it felt more like dark fantasy or horror. Anyway, angels and miracles abound on Earth, proving the existence of God. But proving He exists isn't the same as discerning His plans for the world. A small group of people who have been touched by tragedies and miracles attempt to discover why God has shaped their lives in the manner that He has chosen.
It reads a little like a synopsis for a longer story but the plot is compelling enough to keep things interesting. A chilling meditation on the nature of faith.
