Remember that the man who truly repents is never satisfied with his own repentance. We can no more repent perfectly than we can live perfectly. However pure our tears, there will always be some dirt in them; there will be something to be repented of even in our best repentance. But listen! To repent is to change your mind about sin, and Christ, and all the great things of God. There is sorrow implied in this; but the main point is the turning of the heart from sin to Christ. If there be this turning, you have the essence of true repentance, even though no alarm and no despair should ever cast their shadow upon your mind.
C.H. Spurgeon
