Romans 4:19-21

New Testament for Everyone

¹⁹ He didn’t become weak in faith as he considered his own body (which was already as good as dead, since he was about a hundred years old), and the lifelessness of Sarah’s womb. ²⁰ He didn’t waver in unbelief when faced with God’s promise. Instead, he grew strong in faith and gave glory to God, ²¹ being fully convinced that God had the power to accomplish what he had promised.
