Abraham bowed down with his face touching the ground, but he began to laugh when he thought, "Can a man have a child when he is a hundred years old? Can Sarah have a child at ninety?"

But God said, "No. Your wife Sarah will bear you a son and you will name him Isaac. I will keep my covenant with him and with his descendants forever. It is an everlasting covenant.

Abraham and Sarah were very old, and Sarah had stopped having her monthly periods.

Then the LORD asked Abraham, "Why did Sarah laugh and say, 'Can I really have a child when I am so old?'

The LORD blessed Sarah, as he had promised,

and she became pregnant and bore a son to Abraham when he was old. The boy was born at the time God had said he would be born.

Remember your relative Elizabeth. It is said that she cannot have children, but she herself is now six months pregnant, even though she is very old.

For the devout women of the past who placed their hope in God used to make themselves beautiful by submitting themselves to their husbands.

Sarah was like that; she obeyed Abraham and called him her master. You are now her daughters if you do good and are not afraid of anything.

Let us hold on firmly to the hope we profess, because we can trust God to keep his promise.

His faith did not leave him, and he did not doubt God's promise; his faith filled him with power, and he gave praise to God.

He was absolutely sure that God would be able to do what he had promised.
