{17} Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall thy seed be.

(17) A description of true faith wholly resting in the power of God, and his good will, set forth in the example of Abraham.

People's New Testament

4:18 Who against hope. Though an old man, and his wife an aged woman, far beyond the time of child-bearing, he yet believed the promise that he would have numerous offspring.

Wesley's Notes

4:18-21 The Apostle shows the power and excellence of that faith to which he ascribes justification. Who against hope - Against all probability, believed and hoped in the promise. The same thing is apprehended both by faith and hope; by faith, as a thing which God has spoken; by hope, as a good thing which God has promised to us. So shall thy seed be - Both natural and spiritual, as the stars of heaven for multitude. Gen 15:5.

Jamieson-Fausset-Brown Bible Commentary

18-22. Who against hope-when no ground for hope appeared.

believed in hope-that is, cherished the believing expectation.

that he might become the father of many nations, according to that which was spoken, So shall thy seed be-that is, Such "as the stars of heaven," Ge 15:5.

Matthew Henry's Concise Commentary

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.
