C.H. Spurgeon emphasizes that true repentance is deeply personal and always accompanied by sorrow for sin. He argues against the modern notion that repentance is merely a change of mind, asserting that it involves a profound transformation of the heart and a genuine mourning for past sins. Spurgeon highlights the necessity of individual acknowledgment of sin, stating that true penitence cannot be communal but must be experienced apart, as each person must confront their own guilt before God. He illustrates this with biblical references, particularly from Zechariah, stressing that each family and individual must mourn separately for their sins. Ultimately, Spurgeon calls for a personal and sincere confession to God, urging believers to seek forgiveness through Christ alone.
