He makes his power and his grace available to us once we are joined to Christ. It is that faith works. But the Sea of Galilee stays fresh because it has an outlet for the water it receives. The Dead Sea lives up to its name because it does not. When we bottle them up inside ourselves, they become stagnant.
Stagnant faith stinks, like stagnant water.
And the world has sensitive nostrils. They are the necessary foundation and precondition for all others. If a person is not courageous, for instance, he will not overcome the difficulties inherent in the practice of any virtue. If he is not wise, he will not understand what he is doing, and his virtue will sink to the level of blind animal instinct. But never less.
