4:14 {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.
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.
