Abraham bowed with his face to the ground and thought, “I am almost 100 years old. How can I become a father? And Sarah is 90. How can she have a child?” So he started laughing.
The chief officer there with the king replied, “I don't believe it! Even if the Lord sent a rainstorm, it couldn't produce that much grain by tomorrow.” “You will see it happen, but you won't eat any of the food,” Elisha warned him.
Abraham's faith never became weak, not even when he was nearly 100 years old. He knew he was almost dead and that his wife Sarah could not have children.
