Many Christians think that there is no law in the new covenant. Yet lawlessness is precisely that which characterizes condemned people (Matt. 7:23). In Christ we have been enabled to obey God and to fulfill His law (Rom. 8:1–8). When we love others as we love ourselves, we will do what is required of covenant keepers (13:8–10). Spend time today reviewing the Westminster Larger Catechism, Questions 91–153, so that you might know what the moral law requires of us.
The way in which the Mosaic law applies to believers today is a contentious matter, and there are many different opinions on the subject even within the Reformed tradition. All agree, however, that the coming of Christ did not suddenly make the Ten Commandments and the other ethical portions of the law of Moses invalid. Let us endeavor to know the moral law, that we might live in a way pleasing to our God.
