Conscience is an inward witness. Other witnesses are without a man, and so may be set aside. One witness may be produced against another, one testimony against another, or circumstances may be alleged to destroy the probability of the testimony given; but it cannot be so where conscience is concerned, for that is a witness within a man.
A man may as soon fly from God, as from his own conscience. It will follow him into all places into all worlds! Nay, he may as soon fly from himself. Wherever he goes, it haunts him, meets him, faces or pursues him; at home and abroad, alone and in company. It presents itself in his thoughts by day, in his dreams by night.
The court of conscience is the court of God, where it acts in his name, and by his authority; as judge, jury, and witness. It speaks when and what he bids it; and when he commands it to be silent, it holds its peace. It is the king's witness, and therefore must not be treated with contempt. It speaks by commission; so that he who heareth conscience, heareth God; he that heareth not conscience, heareth not God.
