osmoregulation means – “Processes by which a cell regulates its internal osmotic pressure. These may include water transport, ion accumulation or loss, synthesis of osmotically active substances such as glycerol in the alga Dunaliella, activation of membrane ATPases etc.”
Could it also be a metaphor for “in the world but not of it”? As a body (of Christ or otherwise) let’s certain things in and keeps others out it has to maintain a level of “osmotic pressure”. Maybe we more osmotic pressure in our faith communities? A dose of “holy tension” would do us good.
