Romans 4:19-21

Living Bible

¹⁹ And because his faith was strong, he didn’t worry about the fact that he was too old to be a father at the age of one hundred, and that Sarah his wife, at ninety,^[a] was also much too old to have a baby.

²⁰ But Abraham never doubted. He believed God, for his faith and trust grew ever stronger, and he praised God for this blessing even before it happened. ²¹ He was completely sure that God was well able to do anything he promised.
