The "fire and brimstone" style is often referred to as a method of preaching that is used by Christian preachers to paint clear images of hell and eternal doom to all people that are living in sin to change their ways and turn to God so he can forgive them.
This style was made popular by Jonathan Edwards when he preached a sermon titled, "Sinners in the hands of an angry God" during the Great Awakening in the United States.
