Death Bed is basically a story about a man, often thought to be Matt Thiessen, but its not, whose father was a pastor and when he was young, he was saved. However, certain things happened in his life that caused him to get away from the faith, become a drunkard, get a girl pregnant marry her, then get divorced.
