Acts 3:19-21

Repent you therefore, and be converted, that your sins may be blotted out…

repentance is practical: — I heard one say, "It is an awful-thing to be a slave to the winecup; I wish that I had never tasted it. The first opportunity I get I will turn over a new leaf." He did not say what the new leaf would be, but he was going to do any quantity of reforming work. Alas I he never did anything at all, for he was drunk again the next day. A beautiful penitent to look upon; but a wretched hypocrite in due time, for he returned like the dog to his vomit, and the sow which was washed to her wallowing in the mire. If you repent of sin, down with sin! In God's name, down with sin! When repentance is hearty it is practical. When a man truly turns to God, he turns away from sin.
