Discontent Has It's Own Punishment

Discontent is a sin that is its own punishment and makes men torment themselves; it makes the spirit sad, the body sick, and all the enjoyments sour; it is the heaviness of the heart and the rottenness of the bones. It is a sin that is its own parent. It arises not from the condition, but from the mind. As we find Paul contented in a prison, so Ahab discontent in a palace.

- Matthew Henry
