Romans 4:19-21

Revised Standard Version Catholic Edition

¹⁹ He did not weaken in faith when he considered his own body, which was as good as dead because he was about a hundred years old, or when he considered the barrenness of Sarah’s womb. ²⁰ No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, ²¹ fully convinced that God was able to do what he had promised.
