As I was walking in the fields, the thought came over me with almost overwhelming power, that every one of my flock must soon be in heaven or hell. Oh how I wished that I had a tongue like thunder, that I might make all hear; or that I had a frame like iron, that I might visit every one and say, Escape for thy life! Ah sinner! You little know how I fear that you will lay the blame of your damnation at my door.
