The following is from a message preached by Thomas Brooks in London in 1659.
"The least sin is very dangerous!
Caesar was stabbed to death with a small needle.
Herod was eaten up by small worms.
Pope Adrian was choked with a gnat.
A scorpion is little, yet is able to sting a lion to death.
The least spark, may consume the greatest house.
The least leak, may sink the greatest ship.
A whole arm has been gangrened, by a pick of the little finger.
A little opened door, may betray the greatest city.
A pinch of poison diffuses itself into all parts, until it strangles
the vital spirits, and turns out the soul from the body.
The least sin is very dangerous!"
