With every bit of revelation we receive from God, with everything that is made known there are also some things that remain hidden in the dark. We see this when God comes to his people Israel when they are at the base of Mt. Siani. At no other time in their life had God revealed himself so completely, and yet there was darkness.
The writer of Exodus tells us plainly after God had spoken the Ten Words, “The people remained at a distance, while Moses approached the thick darkness where God was” (Exodus 20.21). This specific Hebrew word araphel speaks of a darkness reserved for God. One that reveals and conceals. Which, if this teaches us anything it is this – even the darkness can reveal God to us.
As the anonymous writer of The Cloud of Unknowing teaches us, “… set yourself to rest in this darkness as long as you can, always crying out after him whom you love. For if you are to experience him or to see him at all, insofar as it is possible here, it must always be in this cloud and in this darkness.”
