I grant that the particular commandments are positive and supernatural; so the justified is obliged by this back-bond and gospel re-obligation to confess sin dwelling in him, to groan, and sigh, and sorrow under it to be troubled and grieved in spirit, for sin as sin dwelling in his members, and rebelling against the law of his mind, and keeping him in bondage; to walk humbly and softly all his days, by reason of the running issue of sin, and to strive by all means to walk worthy of Christ.
