Theological Term of the Week

There is a bit of disagreement over the legitimacy of the third use of the law. The quotes and links included reflect this.

third use of the law
The use of the law’s moral standards as a guide to God’s will for the believer’s conduct; the use of the law as a “sure rule and standard of a godly life and walk.”1

• From the Westminster Confession of Faith, Chapter 19, Of the Law of God:

VI. Although true believers be not under the law, as a covenant of works, to be thereby justified, or condemned; yet is it of great use to them, as well as to others; in that, as a rule of life informing them of the will of God, and their duty, it directs and binds them to walk accordingly….

• From Institutes of the Christian Religion, Book 2, Chapter 7, by John Calvin:

12. The third use of the Law (being also the principal use, and more closely connected with its proper end) has respect to believers in whose hearts the Spirit of God already flourishes and reigns. For although the Law is written and engraven on their hearts by the finger of God, that is, although they are so influenced and actuated by the Spirit, that they desire to obey God, there are two ways in which they still profit in the Law. For it is the best instrument for enabling them daily to learn with greater truth and certainty what that will of the Lord is which they aspire to follow, and to confirm them in this knowledge; just as a servant who desires with all his soul to approve himself to his master, must still observe, and be careful to ascertain his master’s dispositions, that he may comport himself in accommodation to them. Let none of us deem ourselves exempt from this necessity, for none have as yet attained to such a degree of wisdom, as that they may not, by the daily instruction of the Law, advance to a purer knowledge of the Divine will. Then, because we need not doctrine merely, but exhortation also, the servant of God will derive this further advantage from the Law: by frequently meditating upon it, he will be excited to obedience, and confirmed in it, and so drawn away from the slippery paths of sin. In this way must the saints press onward, since, however great the alacrity with which, under the Spirit, they hasten toward righteousness, they are retarded by the sluggishness of the flesh, and make less progress than they ought. The Law acts like a whip to the flesh, urging it on as men do a lazy sluggish ass. Even in the case of a spiritual man, inasmuch as he is still burdened with the weight of the flesh, the Law is a constant stimulus, pricking him forward when he would indulge in sloth. David had this use in view when he pronounced this high eulogium on the Law, “The law of the Lord is perfect, converting the soul: the testimony of the Lord is sure, making wise the simple. The statutes of the Lord are right, rejoicing the heart: the commandment of the Lord is pure, enlightening the eyes,” (Ps. 19: 7, 8.) Again, “Thy word is a lamp unto my feet, and a light unto my path,” (Ps. 119: 105.) The whole psalm abounds in passages to the same effect. Such passages are not inconsistent with those of Paul, which show not the utility of the law to the regenerate, but what it is able of itself to bestow. The object of the Psalmist is to celebrate the advantages which the Lord, by means of his law, bestows on those whom he inwardly inspires with a love of obedience. And he adverts not to the mere precepts, but also to the promise annexed to them, which alone makes that sweet which in itself is bitter. For what is less attractive than the law, when, by its demands and threatening, it overawes the soul, and fills it with terror? David specially shows that in the law he saw the Mediator, without whom it gives no pleasure or delight.

• From 40 Questions About Christians and Biblical Law by Tom Schreiner:

Strictly speaking, the idea that believers are under the third use of the law is mistaken, for we have seen that the entire law is abolished for believers. Still, the notion is not entirely wrong since Paul’s teaching is filled with exhortations that call upon believers to live in a way that pleases God. …[S]ome of the commands are from the Old Testament law, and surely they function as a standard for the lives of believers today. Still, derivation from the Old Testament does not make them authoritative. They are God’s will for human beings because they represent God’s character. Even though the Old Testament law is not literally binding upon believers, we see principles and patterns and moral norms that still apply to us today since the Old Testament is the word of God.

• From Living for God’s Glory by Joel Beeke:

The law of God is the standard for Christian conduct. It reveals the character of God and His perfect righteousness. The origin of the law is the will of God, which is neither arbitrary or capricious. Because the law expresses God’s unchangeable holiness and righteousness, it endures forever. …

Calvinist ethics … also recognizes three uses of the divine law. First, like a bridle, the law restrains the wickedness of unregenerate people. Second, like a mirror, the law shows people their sin and their need of Jesus Christ. Finally, like a map, the law guides God’s redeemed children along the way of living faithfully before Him. Throughout its history, Reformed ethics has stressed the positive use of the law in the Christian life in teaching believers grateful obedience to God.

Status Report: May

Sitting…on the couch next to a cuddly dog. Yes, I let the big dog up on the couch. Sometimes I regret it, like when I vacuum, but sometimes I don’t, like right now.

Thanking God…for my youngest daughter who turned 28 yesterday. I made a cake to celebrate—a chocolate cake using Miracle Whip instead of eggs or oil—and it was delish. I chose the recipe to avoid making a trip to the grocery store for supplies, and Plan B turned out best by a long shot.

Realizing…my little granddaughter is a social butterfly, and a bit of a show-off, to boot. Yesterday was her 7 month birthday; she spent the evening entertaining her extended family. It was more fun than a carnival and a parade rolled into one.

Wondering…when that last little patch of snow in my front yard will finally be gone. I’m pretty sure it should have mozied on down to the southern hemisphere by now.

Also wondering…why my spell check always underlines thank, thanking, and thankful, and then has thank, thanking or thankful as suggested alternatives. What’s up with that?

Feeling…pleased that my tax refund check arrived in the mail today, along with my replacement credit card. Oh, and several books I ordered, too. It’s been an excellent day, mail-wise.

Reading…several books: The Hammer of God by Bo Geirtz; Pierced for Our Transgressions by three guy I don’t remember; God’s Battalions: The Case for the Crusades by Rodney Stark; and Wordsmithy by Doug Wilson. I finished the first novella in The Hammer of God this morning, and I’ll let that book sit for a bit before I take it up again. Not because I’m not enjoying it, but because when I start a story, I can’t stop reading until it’s finished. 

Finishing…up, because that’s all the time I have.

Leaving…to make supper. 

Round the Sphere Again: Scripture

Internal Unity
Tim Challies pinned this infographic on Pinterest. I like it; I wish I had a use for it—other than just looking at it, that is. Maybe you have a use for it.

Not Necessarily Prescriptive
Kim Shay makes a very important point about how not to interpret the book of Acts. (The Upward Call).

Not everything in a narrative is normative. Our task is, of course, to discern which is and which is not. The unique situation with Acts is that everyone wants to think it’s normative. 

All or Nothing
From Sarah Flashing at The Center for Women of Faith in Culture:

When the Bible is viewed as a collection of writings–some inspired and some not–filled with erroneous sayings and irrelevant principles for living, it becomes more of a tangled mess rather than a beautifully woven pattern of God’s orderly self-disclosure. … At this point, it seems there’s no point in pursuing God within the pages of scripture.
