Bliss: A Knot of Riddles: I. Fish in River. Slowly Flowing

My abode's not Silent, but I am Not loud-mouthed. The Lord Almighty Laid down laws for both of Us together. I am swifter than him who harbors me, And sometimes stronger too. He must strive more potently. At times I just Relax, while he must needs Run onward. But I live in him all the Days of my life. If we're ever divided by Destiny, 'tis Death. And the answer: Fish in river.
