Satan the Coward

Satan is a great coward. He will generally meddle with God's people when they are down. I find that when I am in good physical health, I am not often tempted of Satan to despondency or doubt; but whenever I get depressed in spirit, or the liver is out of order, or the head aches, then comes the hissing serpent.
