God, we thank you for the faith of Sarah. As you teach us in Hebrews 11:11, we do not to despise this matriarch for her initial laughter at your promise, but rather emulate her subsequent trust in you, the faithful One. Truly there is nothing too wonderful that you cannot do it. Please graciously grant us power to serve you as Sarah did as you advance your sweet purposes in the Messiah. Amen.
