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

Romans 4:20,21 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; …
Romans 14:21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.

considered.
Genesis 17:17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?
Genesis 18:11-14 Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women…
Hebrews 11:11-19 Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised…
He acknowledged the decrepitness of his body
Abraham's recognition of his own physical limitations underscores the miraculous nature of God's promise. At nearly a hundred years old, his body was naturally beyond the age of fathering children. This acknowledgment is not a sign of doubt but rather an honest assessment of his situation, which makes his faith even more remarkable. It parallels the human condition of recognizing our limitations and relying on divine intervention, as seen in 2 Corinthians 12:9, where God's power is made perfect in weakness.
(since he was about a hundred years old)
This detail emphasizes the improbability of Abraham fathering a child at such an advanced age, reinforcing the miraculous nature of Isaac's birth. Genesis 17:17 records Abraham's initial reaction to God's promise, where he laughs at the idea of having a child at such an age. This historical context highlights the cultural understanding of old age and childbearing, making the fulfillment of God's promise even more significant.
And the lifelessness of Sarah’s womb
Sarah's barrenness is a recurring theme in the narrative of Abraham's life, first mentioned in Genesis 11:30. Her inability to conceive is a significant obstacle to the fulfillment of God's promise to make Abraham a great nation. This situation sets the stage for God's intervention, demonstrating His power to bring life where there is none. It also serves as a type of the virgin birth of Jesus Christ, where God brings about life in a miraculous way, as seen in Luke 1:34-35.
Paul highlights Abraham’s steady confidence in God despite long years of waiting.
• Faith here is not naïve optimism; it is a settled trust rooted in God’s promise (Genesis 15:5-6).
• Hebrews 11:17-19 echoes this unwavering posture, showing that true faith perseveres when circumstances shout the opposite.
• James 1:6 warns against doubting; Abraham models the opposite—he “did not waver.”
Abraham dealt with facts, not denial.
• Genesis 17:17 records him knowing his own age, yet still believing.
• Recognizing reality enhances, rather than diminishes, faith; it magnifies God’s glory when He overcomes impossible odds (2 Corinthians 12:9).
• By admitting weakness, Abraham positioned himself to see God’s strength displayed (Romans 4:20).
Sarah’s barrenness was long-standing (Genesis 11:30), humanly irreversible.
• Hebrews 11:11 credits Sarah with receiving power to conceive when she, too, believed.
• God often waits until resources are exhausted so His intervention is unmistakable (Judges 7:2).
• The promised child, Isaac, thus became a living testimony that nothing is too hard for the Lord (Genesis 18:14).
Romans 4:19 shows that biblical faith faces realities head-on yet refuses to let them overrule God’s promise. Abraham saw his own frailty and Sarah’s barrenness, but these facts only underscored the certainty that God would act. True faith is not weakened by impossibility; it is strengthened, knowing that the God who speaks is also the God who performs what He has promised.
(19) Considered not.--The negative should, in accordance with the evidence of the best MSS., be emitted. "Who, because he was not weak in faith, considered indeed--took full account of--the natural impediments to the fulfilment of the promise, and yet did not doubt."
