14 For if they which are of the law be heirs, faith is made void, and the promise made of none effect:
English Standard Version
14 For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void.
14 If those who get what God gives them only get it by doing everything they are told to do and filling out all the right forms properly signed, that eliminates personal trust completely and turns the promise into an ironclad contract! That's not a holy promise; that's a business deal.
New King James Version
14 For if those who are of the law are heirs, faith is made void and the promise made of no effect,
New Living Translation
14 If God's promise is only for those who obey the law, then faith is not necessary and the promise is pointless.
The promise was made to Abraham long before the law. It points at Christ, and it refers to the promise, Genesis 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.
