The Mercy of God in Preventative Providence

When the story of David and Nabal begins, David is prepared to repay with the violence the insult of Nabal by taking matters into his own hands, an action of vengeance that would have been a blot on his character for the rest of his life. God intervenes with preventive providence through Abigail to save Nabal and his men from David's violent vengeance, but in doing so, Abigail was God's instrument to save David from himself. In the beginging David had only asked for the compensation which was rightly his for services rendered, In the end, God gives to David everything which belonged to Nabal.
