It takes true wisdom to work around people who are only about themselves, people who are in the flesh. Abigail chose to act even though by the definition of the roles she should have "submitted."  In today's world what we call submission is our excuse for doing nothing; God is calling us to act. Abigail acted and even prophesied to David before he was king to keep things from ending badly. True submission has strength and courage to it. It is not weakness masquerading as a virtue.
