"Or do you despise the riches of His goodness, forbearance, and longsuffering, not knowing that the goodness of God leads you to repentance? But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgment of God..." (Rom. 2:4-5)

What would you think of a doctor who, on discovering you had a tumor buried deep in your body, responded, "Take two aspirin and you'll be just fine." How about a fireman who responded to a three-alarm fire by saying, "It'll probably burn itself out soon enough," or a policeman who, on arriving at the scene of a robbery, merely shook his head and said, "Boys will be boys!" In each case the response is inappropriate to the situation. (From 1500 Illustrations for Biblical Preaching, p. 346)

Often, man's response to sin is far to inappropriate. A hard and impenitent heart brings God's eternal wrath.
