Romans 4:19-21

Verse

19 Without weakening in his faith, he acknowledged the decrepitness of his body (since he was about a hundred years old) and the lifelessness of Sarah’s womb. 20 Yet he did not waver through disbelief in the promise of God, but was strengthened in his faith and gave glory to God, 21 being fully persuaded that God was able to do what He had promised.
