How does God's intervention change the circumstances in Genesis 20?

God intervenes in the story of Genesis 20 by sending a dream to Abimelech, warning him that Sarah is another man's wife. This divine act prevents sin and highlights God's authority over human circumstances. It serves as a powerful reminder that God orchestrates events for His purpose and the good of His people. His intervention not only protects Sarah but also reaffirms the promise made to Abraham about the lineage through which the Messiah would come, emphasizing God's faithfulness to His covenant.
