"The whole life of Christians ought to be an exercise of piety, since they are called to sanctification. It is the office of the law to remind them of their duty and thereby to excite them to the pursuit of holiness and integrity. But when their consciences are solicitous how God may be propitiated, what answer they shall make, and on what they shall rest their confidence, if called to his tribunal, there must then be no consideration of the requisitions of the law, but Christ alone must be proposed for righteousness, who exceeds all the perfection of the law."
