Genesis 17:15
“God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but her name will be Sarah.”
What does Genesis 17:15 mean?
God changes Sarai's name to Sarah, and while it might seem like a small edit, the shift matters deeply. Both names relate to words meaning "princess," but Sarah carries a broader, more universal quality, while Sarai was more personal and specific. This renaming signals that God is expanding his covenant promise, opening the blessing of motherhood not just to Abraham's household but through a lineage that would grow into nations. When God renames someone in Scripture, it's always because their identity or calling is being transformed or clarified. For Sarai, this name change acknowledges her before she even becomes pregnant, declaring her true identity as the mother of nations before circumstances reflect it. It's a quiet but profound act of God speaking her future into existence.
