Explanation:

When electricity charges the metallic wire, the wire is treated as electricity. The electric wire is seen but you can say that the electricity is seen. The electricity is seen through the wire indirectly, although not directly. Electricity pervades all over the wire and when the wire is touched anywhere, the electricity is experienced through the touch of the wire. Therefore, the verbs like seen, touched etc., apply to the wire and not to the electricity. But indirectly, the electricity is experienced through the shock. Similarly, God is experienced through the medium, since the medium can be treated as God like the live wire.

[1] Mediated God means God in a medium. More specifically, for human beings on Earth, it means God-in-human-form or the Human Incarnation.
