For if they which are of the law - Who seek for justification and acceptance by the Law.

Faith is made void - Faith would have no place in the scheme; and consequently the strong commendations bestowed on the faith of Abraham, would be bestowed without any just cause. If people are justified by the Law, they cannot be by faith, and faith would be useless in this work.

And the promise ... - A promise looks to the future. Its design and tendency is to excite trust and confidence in him who makes it. All the promises of God have this design and tendency; and consequently, as God has given many promises, the object is to call forth the lively and constant faith of people, all going to show that in the divine estimation, faith is of inestimable value. But if people are justified by the Law; if they are rendered "acceptable" by conformity to the institutions of Moses; then they cannot depend for acceptance on any promise made to Abraham, or his seed. They cut themselves off from that promise, and stand independent of it. That promise, like all other promises, was made to excite faith. If, therefore, the Jews depended on the Law for justification, they were cut off from all the promises made to Abraham; and if they could be justified by the Law, the promise was useless. This is as true now as it was then. If people seek to be justified by their morality or their forms of religion, they cannot depend on any promise of God; for he has made no promise to any such attempt. They stand independently of any promise, covenant, or compact, and are depending on a scheme of their own; a scheme which would render his plan vain and useless; which would render his promises, and the atonement of Christ, and the work of the Spirit of no value. It is clear, therefore, that such an attempt at salvation cannot be successful.

For, if they which are of the law be heirs - If the Jews only be heirs of the promise made to Abraham, and that on the ground of prior obedience to the law, then faith is made void - is entirely useless; and the promise, which was made to faith, is made of none effect.

For if they which are of the law be heirs,.... That is, if the Jews who are under the law, and are seeking for righteousness and life by the works of it, should, on the account of their obedience to it, be heirs of the grace of life and of glory,

faith is made void; for if the right to the inheritance is by the works of the law, there is no room for faith; that can be of no use or service;

and the promise made of none effect: if salvation is by works, it is to no purpose for God to promise, or men to believe; for the thing promised depends not upon God's promise, but upon man's obedience to the law; and if that is not perfectly observed, as it cannot possibly be, then the promise of God stands for nothing, and is in course made void. The apostle here argues from the absurdities which follow upon the doctrine of justification by works, as he does from the different effects of the law, in the following verse.

{12} For if they which are of the {k} law be heirs, faith is made void, and the promise made of none effect:

(12) A double confirmation of that reason: the one is that the promise cannot be apprehended by the law, and that if it could it would be made of no effect: the other, that the condition of faith would be joined in vain to the promise if it could be apprehended by works.

(k) If they are heirs who have fulfilled the law.

4:14 For if they who are of the law are heirs. Of law, the article wanting. If keeping law makes men heirs, then

faith is made void. It sets aside God's plan of counting faith as righteousness, and destroys the promise which depends on faith.

4:14 If they only who are of the law - Who have kept the whole law. Are heirs, faith is made void - No blessing being to be obtained by it; and so the promise is of no effect.

14. For if they which are of the law be heirs-If the blessing is to be earned by obedience to the law.

faith is made void-the whole divine method is subverted.

4:13-22 The promise was made to Abraham long before the law. It points at Christ, and it refers to the promise, Ge 12:3. In Thee shall all families of the earth be blessed. The law worketh wrath, by showing that every transgressor is exposed to the Divine displeasure. As God intended to give men a title to the promised blessings, so he appointed it to be by faith, that it might be wholly of grace, to make it sure to all who were of the like precious faith with Abraham, whether Jews or Gentiles, in all ages. The justification and salvation of sinners, the taking to himself the Gentiles who had not been a people, were a gracious calling of things which are not, as though they were; and this giving a being to things that were not, proves the almighty power of God. The nature and power of Abraham's faith are shown. He believed God's testimony, and looked for the performance of his promise, firmly hoping when the case seemed hopeless. It is weakness of faith, that makes a man lie poring on the difficulties in the way of a promise. Abraham took it not for a point that would admit of argument or debate. Unbelief is at the bottom of all our staggerings at God's promises. The strength of faith appeared in its victory over fears. God honours faith; and great faith honours God. It was imputed to him for righteousness. Faith is a grace that of all others gives glory to God. Faith clearly is the instrument by which we receive the righteousness of God, the redemption which is by Christ; and that which is the instrument whereby we take or receive it, cannot be the thing itself, nor can it be the gift thereby taken and received. Abraham's faith did not justify him by its own merit or value, but as giving him a part in Christ.
