Matthew 27:3

Repented himself; he knew that Jesus was innocent, and yet he had been instrumental in delivering him to his murderers. He was therefore tormented by a conviction of his guilt. The evil of committing known sin is greater than sinners imagine; while the pleasure which they derive from it is less, and is nothing compared with the pain which it will give them. The commission of one sin not only opens the door and prepares the way for the commission of others, but leads to consequences which the sinner little imagines, and the contemplation of which fills him with horror. A deep conviction of sin, and the most pungent distress on account of it, full confession of guilt, and readiness to return the wages of iniquity, may all exist without true repentance, without any love to God and holiness, or any preparation for heaven.
