When Abram was ninety-nine years old, the LORD appeared to him and said, "I am the Almighty God. Obey me and always do what is right.

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?"

He was then almost one hundred years old; but his faith did not weaken when he thought of his body, which was already practically dead, or of the fact that Sarah could not have children.
