You cannot see or touch the unseen that forms the foundation of faith. But you can observe the changes that occur in the person's life when he places his confidence in the unseen. Faith cannot and must not be restricted to the single expression of obedience. Faith always exists and is constantly expressing itself. It is not confined to the moment of the act of obedience.
Obedience is an essential expression of faith.
But it is not the only expression of faith. In fact, all other expressions of faith are just as powerful and just as important as obedience. Our personal goal as a Christian man or woman must to be express faith in all of its forms.
