Dangers seen and unseen

"Deliver us from dangers, both seen and unseen." The old brethren who offered public prayer in my childhood would frequently use this expression. As the years have passed, it has come to mean more and more to me. I know certain perils that face me, but there is much out there that could hurt me of which I am not even aware. But God knows, and He is able to deliver us from what we see, and what we do not see.
