WCF 19: Of the Law of God

 By William Boekestein - Posted at Place for Truth:

Unlike every other religion Christianity is fundamentally a message of grace. True believers are “not under the law, as a covenant of works, to be thereby justified or condemned” (cf. Rom. 6:14) Believers are saved by grace alone through faith alone in Christ alone.

But a misunderstanding of grace leads to a confused relationship with the law. Some think that any loyalty to law indicates legalism. Others ridicule God’s law, calling it inconsistent. After all, they reason, Old Testament prohibitions against homosexuality run alongside rules against mixing seeds in a field and materials in a garment (Lev. 18:22; 19:19; 20:13). Even Christians who are conscientious about God’s law can be unclear about which obligations are enduring and which have been fulfilled. We need a better understanding of God’s law so that we can use it in a way that honors him.

How Should I Understand God’s Law?

The principle of God’s law is very simple. The Creator imposes his values on his creatures. That truth never changes. In fact, in the New Testament Christ doubles-down on the necessity of rigorous obedience. In the Sermon on the Mount sincere submission to God’s law distinguishes citizens of God’s kingdom from citizens of the world. The law contrasts for us good works and works of the flesh. And we need that distinction. We must do good works which are only those “God hath commanded in his holy word” (16.1).
