It reminded me of an ex sister-in-law, Joyce, who was a nurse many years ago. I remember her telling me that she didn't allow illness to exist in her ward. I could imagine from her tone of voice as she said it that any patient would feel safe in her ward. Why shouldn't they, this powerful person looking after them wouldn't allow illness past the doors. The illness could stay outside. . . and 'be afraid'!
I am minded of an old song too that went, "be not afraid for I am with you all the time. . . " The 'I' can be what you will, perhaps the sense of an expanding universal power that carries you safely with it.
Just a thought. . . and sometimes it will be just a thought that turns the tables.
