“There is, in the world, a great deal of sorrow on account of sin which is certainly not repentance and never leads to it. Some transgressors are sorry for sin for a time—they are convicted of guilt with a transitory conviction which soon passes away. Many are sorry for sin because of its temporal consequences—and many more because of its eternal consequences. They are afraid of Hell. If there were no Hell, they would like to continue to live in sin. . . . They are as fond of sin as ever they were, but they sorrow because they see that it is bringing them down to the gulf of Perdition. Now, that kind of sorrow is not repentance! A moth may burn its wings in the candle and then, full of pain, fly back to the flame. There is no repentance in the moth, though there is pain—and so, there is no repentance in some men, though there is in them a measure of sorrow on account of their sin. Do not, therefore, make a mistake in this matter, and think that sorrow for sin is, or even necessarily leads to, repentance.”

– Charles Spurgeon (“Sorrow & Sorrow” sermon.)
