(excerpt from Morning Meditations by Martin Wiles)
Isaiah 6:6-7 Then one of the seraphs flew to me with a live coal in his hand, which he had taken with tongs from the altar. With it he touched my mouth and said, “See, this has touched your lips; your guilt is taken away and your sin atoned for.” (NIV)
I noticed it immediately after eating out my first time while visiting Canada. I had encountered the same scenario in New England.
