What is that power, that ability that keeps one going in the fade of opposition? David had it when he faced the giant, Goliath, though the army did not. Paul the Apostle had it when the mob stoned him and left him for dead. These men and many others went on to greatness because they had the quality of Dynamic Fortitude. And you can have it too.
AS a matter of fact, it is essential to living the Christian way of life in order to hear "Well done good and faithful servant."
