And being not weak in faith - That is, having strong faith.

He considered not - He did not regard the fact that his body was now dead, as any obstacle to the fulfillment of the promise. He did not suffer that fact to influence him, or to produce any doubt about the fulfillment. Faith looks to the strength of God, not to second causes, or to difficulties that may appear formidable to man.

Now dead - Aged; dead as to the purpose under consideration; compare Hebrews 11:12, "As good as dead." That is, he was now at an age when it was highly improbable that he would have any children; compare Genesis 17:17.

Deadness ... - Hebrews 11:11, "When she was past age;" compare Genesis 18:11.

He considered not his own body now dead - He showed at once the correctness and energy of his faith: God cannot lie; Abraham can believe. It is true that, according to the course of nature, he and Sarah are so old that they cannot have children; but God is almighty, and can do whatsoever he will, and will fulfill his promise. This was certainly a wonderful degree of faith; as the promise stated that it was in his posterity that all the nations of the earth were to be blessed; that he had, as yet, no child by Sarah; that he was 100 years old; that Sarah was 90; and that, added to the utter improbability of her bearing at that age, she had ever been barren before. All these were so many reasons why he should not credit the promise; yet he believed; therefore it might be well said, Romans 4:20, that he staggered not at the promise, though every thing was unnatural and improbable; but he was strong in faith, and, by this almost inimitable confidence, gave glory to God. It was to God's honor that his servant put such unlimited confidence in him; and he put this confidence in him on the rational ground that God was fully able to perform what he had promised.

And being not weak in faith,.... Abraham was not weak in the exercise of his faith, on the promise of God; nor was his faith weakened about the accomplishment of it, neither by the length of time after the promise was made, nor by the seeming insuperable difficulties of nature which attended it; for

he considered not his own body now dead. The Alexandrian copy reads without the negative, "he considered his own body now dead", and so the Syriac version: which makes his faith the greater, that though he did consider his case, yet his faith was not weakened: the phrase, "his body now dead", is an "euphemism" of the "merebrum virile", which by the Jews, when unfit for generation, is called , "merebrum emortuum" (t):

when he was about an hundred years old; not being quite an hundred years of age, wanting a year or thereabout:

neither yet the deadness of Sarah's womb; how unfit she was to conceive and bear children: now though he might consider these things in his mind, yet they did not dwell upon his mind, nor he upon them; at least he did not consider them, so as to distrust the divine promise.

(t) T. Bab. Yebamot, fol. 55. 2. & Gloss. in ib. Sanhedrin, fol. 55. 1. & Gloss in ib. Shebuot, fol. 18. 1.

Being not weak in faith he considered not (μὴ ἀσθενήσας τῇ πίστει οὐ κατενόησεν)

The best texts omit οὐ not before considered. According to this the rendering is as Rev., he considered, etc. Being not weak or weakened: (Rev.) is an accompanying circumstance to he considered. He considered all these unfavorable circumstances without a weakening of faith. The preposition κατά in κατενόησεν considered, is intensive - attentively. He fixed his eye upon the obstacles.

Dead (νενεκρωμένον)

The participle is passive, slain. Used here hyperbolically. Hence, Rev., as good as dead.

And being {p} not weak in faith, he considered not his own body now {q} dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:

(p) Very strong and steadfast.

(q) Void of strength, and unfit to have children.

4:19 Being not weak in faith. Strong in faith, though weak in body.

His own body now dead. Its vital powers exhausted. But God could quicken the dead, and he had the promise of God.

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.

19. he considered not, &c.-paid no attention to those physical obstacles, both in himself and in Sarah, which might seem to render the fulfilment hopeless.

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.
