"The Covenant Promise Renewed"Genesis 17:21.

In Genesis 17:21, God reaffirms his covenant promise to Abraham, stating that Sarah will indeed bear a son, whom they will name Isaac. This passage reaffirms the divine promise made earlier to Abraham regarding the birth of a son who would be the fulfillment of God's covenant with him. Despite Sarah's initial disbelief due to her old age, God assures Abraham that the promise will be fulfilled according to His will and timing. This verse underscores the faithfulness of God in fulfilling his promises, even in seemingly impossible circumstances, and highlights the importance of trust and obedience in the covenant relationship between God and His people.
