Grace acts secretly, but often it bursts out in the open, in holy outbursts and deeds… there is fire inside wood but it is hidden. Rub a piece of wood against another piece, and you get smoke :: then fire appears.
There is electricity in amber and sealing wax but it is not visible. Rub a piece and immediately you will notice the attraction of small particles and even some sparking.
The telegraph is also silent, but as soon as the device begins to produce friction, electricity immediately awakens and acts swiftly.
